Thursday was a very different kettle of fish at the Brackenfell Public Library compared to Tuesday. No sun, lots of low gray clouds and a cold, blustery north-westerly wind. We implemented plan-B and moved inside, as discussed previously with the library staff. Amanda helped us get organized in the library hall and pointed out the spots in the foyer we could use for posters and A-frames.
Despite putting up notices inviting people to come and flummox us with their astronomy queries we had the grand total of two visitors the entire morning. Those two were actually old friends, Billy and Halcyone Brits who had heard that we would be there and come specially to see us.
The afternoon wasn’t much better as the cold weather seemed to have thinned out the number of learners quite drastically too. Following Lynnette’s suggestion, we gave a talk to the small group that was there. This talk was one we had previously compiled with input from the staff at Boesmansrivier Primary School for use with their learners. The talk was quite enthusiastically received by the learners present. Their enthusiasm was, in fact, at times more than just a bit rowdy!
Murphy saved his final trick for the end of the day. When we tried to start the Vito and leave for home it refused point blank. Not too much of a problem as I had a spare battery at home. We phoned a friend who nipped round, picked me up and dropped me at home. I picked up the spare battery, popped it into the boot of the Polo, and headed back to the Library where Lynnette was waiting.
Murphy now played his next trick. The new battery was about one millimeter too large to fit into the battery compartment of the Vito and the battery leads were too short to reach the battery in any other place outside the battery compartment, where we would be able to shut the door. Lynnette and I quickly ran through plans C to Y before I hit on plan-Z. I connected the spare battery and, while I was holding it, Lynnette started the Vito. Lynnette then kept the engine running quite fast and I disconnected the spare battery, connected the old battery, and slid that into the battery compartment. It all worked perfectly without any shocks, sparks or short-circuits. I was very careful not to throw a clearly crestfallen Murphy the middle finger as he has a very long memory.
Lynnette drove the Polo home and I followed in the Vito, finally bringing the day to a close.
We set up just outside the entrance to the Brackenfell Public Library. The forecast said it would be a sunny day so we also put up our gazebo and decorated that with some of our banners. The banners look nice, provide added wind protection, make the gazebo sturdier and also help prevent uncontrolled access. Sunelle, Lötter and her staff used the material we gave them, predominantly from our own stocks, to put up displays in the entrance foyer and several other parts of the library
As we have experienced in the past it takes a lot of effort to get the public to come and take a look, despite the fact that the telescope was very visible, as were our A-frames and pull-up banners. One has to resort to accosting people, as they approach the entrance and begging them to come and take a peek at the Sun and its lonely sunspot.
This all changed dramatically during the afternoon when the schools closed; we were almost inundated! The Library serves as a focal point for learners whose parents are at work as they also use the library hall to do their homework. The youngsters from the apartments across the road from the library simply use the library and environs as an entertainment area. For the latter group, our presence was a welcome added attraction to their normal routine.
Thanks to the sunny weather and the eager learners it was eventually quite a pleasant and productive outing.
Lynnette and I set up Lorenzo in the rooftop parking area of the Family Pick & Pay on the corner of Old Paarl Road and H.O. De Villiers Street in Brackenfell. The event had been advertised via local social media sites and announcements were also made by the store manager during the course of the evening.
The turnout was disappointingly low but the few people that did turn up were very enthusiastic, which compensated for the poor attendance.
The first Southern Star party held at Leeuwenboschfontein was a success. So, any suspicions about unlucky 13 were neatly sidestepped or perhaps the jinx only applies to people who suffer from triskaidekaphobia.
Lynnette, Snorre and I arrived on Wednesday the 22nd, downloaded our stuff at Dalzicht and set about getting the shed converted into a lecture area with a display section. Fortunately, their spacious kitchen made organising the coffee area very easy.
Jim Adams (speaker), Jonathan Balladon, Deon Begeman, Ronelle Begeman, Steyn Botha, Samuel Botha, Dominique Brink, Johan Brink, Nellie Brink, Anja Bruton, Alan Cassells, Rose Cassells, Pamela Cooper, Chris de Coning, Micah de Villiers, Pierre de Villiers, Barry Dumas, Miemie Dumas, Clair Engelbrecht, Dwayne Engelbrecht, Arné Esterhuizen, Iain Finlay, Edward Foster, Lynnette Foster, Louis Fourie, Maureen Helman, Cheyenne Kersting, Christine Kersting, Harald Kersting, Jamie Kersting, Evan Knox-Davies, Dianne Nxumalo-Kohler, Robin Kohler, Bennie Kotze, Paul Kruger, Lia Labuschagne, Eddy Nijeboer, Jannie Nijeboer, Lorenzo Raynard (speaker), Kim Reitz, Marius Reitz, John Richards, Rogan Roth, Johan Roux (Jnr), (Johan Jnr’s wife), (Johan Jnr’s eldest son), (Johan Jnr’s 2nd son), Alecia Roux, Henda Scott, Barry Shipman, Auke Slotegraaf, Corne van Dyk, and Chris Vermeulen, Alex Wright.
Some of the keen people pitched on Thursday and among them were Deon and Ronelle Begeman. Deon had, as promised at the previous SSP in Bonnievale, constructed two magnificent binocular viewing tripods for Auke and myself. This is really quite an ingenious device with many improvements over what is currently on the market and it is very reasonably priced too when compared to its competitors. I will do a separate post with pictures about it at a later stage.
On Thursday evening Paul and I went up Swartberg in his 4×4. It was a whole lot easier than walking up but also considerably more taxing on one’s nerves and I am not implying that Paul drove recklessly; quite the contrary. It is just that the vehicle adopts a wide variety of very unusual angles during both the ascent and descent and one has to trust the driver a whole lot more than when driving down a normal road.
TOP LEFT: We had some magnificent thunderclouds on Thursday. TOP RIGHT: Paul snapped his first lightning bolt from the top of Swartberg. BOTTOM LEFT: Paul’s night shot of the Leeuwenbosch complex from the top of Swartberg. BOTTOM RIGHT: Paul’s early morning shot of the hut and his pickup.
Arne and Alex had their vehicle expire on the R318 while on the way to the SSP, but they were picked up by Evan and brought to Leeuwenboschfontein. The two seemed pretty laid back about leaving the car at the side of the road until Monday when they would set about sorting it out from Cape Town.
The beginner’s session at the telescopes was quite successful on Friday as was the beginners talk on Saturday morning.
Jonathan had to leave suddenly on Saturday morning as he was needed to fly a plane somewhere. He promised he would flash his landing lights if his route took him over Leeuwenboschfontein which it apparently didn’t.
During my beginners’ session on Saturday morning, Jim Adams, retired Deputy Chief Technologist at NASA and Anja Bruton Science Engagement Coordinator at the SKA arrived. The problem was that Lorenzo Raynard Communications Manager at the SKA, who was due to give the first talk had not pitched and all efforts to contact him were unsuccessful. Jim, hearing of our predicament, very kindly agreed to give the talk he was scheduled to give that afternoon in Lorenzo’s slot. So we started off with “Spinoff: How investing in astronomy and space science changes life on Earth”. Jim proved to be every bit as good a speaker as Anja had said he was; relaxed, knowledgeable and very good at fielding questions too.
In the meantime, Lynnette and Anja were frantically trying to trace Lorenzo.
Martin Lyons and his wife Pat flew in (literally) especially for the social braai in the lapa at the campsite during lunchtime on Saturday. They stayed until after lunch and then flew home again. According to Paul and Louis, the takeoff was actually quite tense but Martin, during subsequent discussions, downplayed any suggestion of problems.
Just before the braai the Vito was attacked by a vicious tree and lost its back window.
By now Lorenzo had been traced and was on his way but would not make it in time for his time slot. We, or at least Anja, talked Jim into giving a second talk in Lorenzo’s slot. This talk “Robots in Space and Space Exploration; Past, Present and Future” went down very well with the audience. Lorenzo finally pitched later on Saturday afternoon. As his talk would cut into observing time we decided to rather have him give his talk on Sunday morning.
After Jim’s talk and the lively question session we took the usual group photograph and, as is usual, some people did not pitch up. People who were absent were Jonathan Balladon, Steyn & Samuel Botha, Dominique & Nellie Brink and Lorenzo Raynard.
The group photograph was followed by the Pub Quiz which, this year, was orchestrated the usual degree of malevolence and cunning by Auke. After several gruelling rounds the overall winner, by a very large margin was Alex. Well done Alex, you left several past winners staggering around in your slipstream’s dust.
The number of beginners at the telescopes on Saturday evening was disappointing but I am hoping it was the sudden drop in temperature that convinced them to stay indoors.
Lorenzo’s talk on Sunday morning. “The public face of SKA in South Africa” was reasonably well attended and, after some discussion, the great dispersal began and the site emptied fairly rapidly. This year, though, more people stayed on to observe the partial solar eclipse on Sunday afternoon.
Dwayne and Claire, who got engaged during the 11th SSP at Night Sky Caravan Farm, missed the 12th SSP because they were getting married. Now, while attending the 13th SSP, Mr and Mrs Engelbrecht announced they were expecting their first child. I suppose it will be too much to expect them to call the baby SSP, but it would be nice if they would.
On Monday morning we packed up and after Calla had very professionally helped close of and dust proof the gaping hole where the Vito’s rear window had been, Lynnette, Snorre and I also left for home.
Anton, Camilla and Viljé stayed on until early February after the rest of the group left on the 15th of January. They moved from Kolping guest house to our place in Brackenfell. Initially, we were a bit concerned because Camilla has a rather serious cat allergy. This was a serious for us too because it is, after all, is said and done, also Snorre’s home. Fortunately, Lynnette’s thorough cleaning coupled with a few restrictions on Snorre’s movements resulted in Camilla never experiencing any discomfort.
During the extended stay we visited several more wineries but, for Lynnette and I, the highlight of the visit was being able to take them to Leeuwenboschfontein ) for two days. Lynnette and I stayed in Bergzicht and Anton, Camilla, Birk and Viljé stayed next door in Dalzicht. Viljé absolutely loved the large lawn, the trampoline and the selection of climbing frames.
At Leeuwenboschfontein the highlight for me was walking up Swartberg to the hut and back with Anton, Camilla and Viljé. We started early at around 07:00 and the climb along the 4×4 track took just over two hours. The distance to walk is a little over 5.5 km during which one gains 300 metres in altitude. The road is very steep in sections and on the way down one has to take extra care not to slip and fall. A crucial point to remember is that there is no water en route and none at the top either.
On the way back we met Johan Roux, the owner of Leeuwenboschfontein, in his pickup taking guests up to the hut. He seemed as surprised to encounter us as I was to find him there on a weekday. He is, after all, based in Ceres and has a business to run. On the other hand if you are the boss you can pretty much do as you please I suppose.
During the climb up Swartberg Lynnette stayed at the guest house looking after Birk and Snorre. We stayed in contact with each other using our two-way radios just in case the climbing group had some sort of accident or she needed us back in hurry. The use of the radios was essential because mobile reception is very erratic at Leeuwenboschfontein and we were uncertain if there would be any reception at all while on the mountain.
When the climbing party got back to the guest house at around lunch time, Lynnette and Birk were relaxing on a blanket under one of the trees on the spacious lawn.
A slightly negative note in connection with Leeuwenboschfontein was the fact that Joan made us pay full price for Viljé. We subsequently discovered that children under the age of six, which Viljé was at the time, actually stay for free.
Without any further ado here are the pictures to tell the story of a memorable and very pleasant stay.
I do not know which of the following is applicable to our case “You cannot have your cake and eat it” or “What you gain on the swings you loose on the roundabouts”. On the one hand we had bright sunshine and a six day old waxing moon that was situated very nicely but, on the other hand, we had a brisk and fairly chilly South-Easter that pushed clumps of fluffy clouds across our field of view all afternoon and, to top it all, there were only two minuscule sunspots visible.
Auke was already there and Eddy and Jannie arrived shortly after us with Dirk about 30 minutes after them. Alan and Rose weren’t there because Alan had to work and Wendy could also not make it as her husband was ill and had been hospitalized.
The brisk South-Easter was quite cold and, as we had suspected the wind drove a never ending series of fluffy clouds across the face of the Moon limiting viewing to the intervening gaps between them. I decided not to even try the Sun as the two diminutive sunspots were really not worth the effort and concentrated on the Moon.
There were fewer people around and this seems to be the pattern when there is a bit of wind. I also think that in the wind people tend to bunch up more at the Swing Bridge and are less inclined to look around. There seems to be a greater sense of urgency to get across. Also for the people coming from the other side they seem to move straight on and not fan out as they do on days when there is less wind.
There were fewer clouds as the afternoon wore on and by sunset we had almost uninterrupted views of the moon. I decided to give viewers a special treat and added a 3x Barlow to my 25 mm eyepiece. That never fails to draw Wows, OMG’s, Awesome’s. Nooo’s and even a You Lie or two from the viewers. It takes a bit more nudging and shoving, but the effect on viewers is more than worth the trouble. In addition Lorenzo has the advantage of being more stable and less prone to wind induced vibrations than the smaller telescopes.
Once the Sun was down it became really chilly and one once again had to marvel at the fact that one could actually show people celestial objects from such a heavily light polluted site as the Pierhead. Unfortunately Venus and Saturn were not well placed for viewing from our position and the best position would have been under the coloured fairy lights on the quayside.
The spring Southern Star Party at Night Sky Caravan Farm (you can visit their Facebook Page here) was a success despite the fact that the weather did not really play along. All in all, 60 people registered, but due to unforeseen circumstances there were cancellations and the final total was 55.
Since the previous SSP in February we have had enough to keep us busy. We were involved in or presented the following events between the previous SSP and this one.
An outreach event at the Kogelberg Farm Hostel for Elkanah House Private School.
A Deep Sky event at Leeuwenboschfontein where we had Klaas and Wilma van Ditzhuyzen from the Netherlands as guests.
The Museum Night at the Iziko Museum in the Company Gardens.
The Friends of the Helderberg Nature Reserve in the Helderberg Nature Reserve.
The Eco Rangers in the Helderberg Nature Reserve.
The Old Age Home in Porterville.
A public event at the Golf course in Porterville.
Four talks at the Durbanville Public Library.
Five public events at the Pierhead in the V&A Waterfront.
Eight days for National Science Week at the Iziko Museum in the Company Gardens.
An outreach event at the !Khwa ttu San Cultural and Educational Centre.
An outreach event at Labiance Primary School.
On Monday the 24th of October shortly after 07:00 Lynnette, Snorre and I left Brackenfell. This time we did not have to work right through the night to finish everything as I had the able assistance of my son, John-Henry. It was not only his physical assistance that made a difference, but his far better eye for what fits in where was a great help. We started unloading as soon as we arrived and during the course of Monday afternoon Tersius and his crew from Bonnievale Verhurings (go here to see more about their activities) arrived to put up the tent.
Alan and Rose Cassells arrived on Tuesday and immediately started setting up their camp site. On Wednesday Eddy Nijeboer arrived with Auke hard on his heels and Barry and Miemie Dumas not far behind him.
This time round the mobile reception was worse than it had ever been at Night Sky and Lynnette and I had no signal whatsoever. This meant that we had to drive back to the R317, where we had a good signal, to receive and read mail. Everyone seemed to have the same problem to a greater or lesser degree except Rose and Alan.
During the course of Wednesday Pamela Cooper, Marius Reitz, John Richards, Wendy Vermeulen, Louis Fourie, Pierre de Villiers, Bennie Kotze and Peter Harvey arrived. By then Night Sky was starting to look populated and discussions were taking place all over the place as people wandered around renewing old acquaintances and making new friends.
On Friday everyone else pitched. Just before the SSP our speaker from Bangalore in India, Amar Sharma had let us know that he was not going to make it due to visa problems. These problems revolved around the slap-dash attitude of the South African diplomatic staff in Mumbai. Amar runs an astronomy tourism operation in Bangalore, (see here). Our other disappointment was that a second speaker, Dr. Wanda Diaz Merced the blind astrophysicist from Puerto Rico, had fallen ill and was hospitalized just a day or two prior to the SSP. We had especially brought along our material used in astronomy outreach for the visually impaired, so that Wanda could demonstrate it. We settled for an exhibition of this material in the tent and it drew quite a lot of attention.
The weather on Friday evening cancelled any possible viewing efforts. Barry Dumas kindly presented a very complete and quite technical talk on optical equipment and what to do and not to do when cleaning it. His talk gave lots of information on the construction of various eyepieces and how special protective materials were applied to both protect and also to improve their optical functionality. After the talk we dispersed and in general spent the rest of the evening watching the clouds and socializing.
Chris Forder was kind enough to lend a hand with some of the younger aspirant astronomer’s telescopes during the course of the weekend. The youthful telescope owners and their parents were all left much the wiser after Chris had finished his explanation.
On Saturday morning I kicked off with the beginners. I handed out all the required paperwork and printed information and talked them through the basics of using star charts. After the beginners, we started the main program and kicked off with Prof. Herman Steyn’s talk on satellites and his work with the University of Stellenbosch’s satellite research section. He was intimately involved with the Rosetta mission and shared many of his experiences with us.
Pierre de Villiers presented a very interesting coverage of the Solar System Model designed and constructed by the Hermanus Centre. This project aims to increase the astronomy awareness of the general public and serve as a permanent outreach installation. The model now forms part of the well known scenic cliff pathway in Hermanus. After Pierre’s talk we had the usual lunchtime braai. Lynnette organized the braai drums as well as the laying and lighting of the fires with the very able assistance of Marius Reitz and Barry Dumas as well as other able bodied assistants.
After lunch we handed out the prizes for the Lucky Draws. This year, instead of depending on the traditional drawing of numbers out of a hat, we did something different. The first person to register, the first person to pay, the first couple to register and the first family to register all received prizes. Auke also decided it was Evan’s birthday and that he should also receive a prize. The fact that it was his birthday was as much a surprise for Evan as it was for the rest of us.
Then it was Auke’s turn to talk about the Centre for Astronomical Heritage. He was followed by Martin Lyons who presented a talk on how to look after your telescope optics. Martin could quite easily take his presentation on tour. With the appropriate musical background and some fancy dance steps it would be an instant comedy hit. However, please do not let the fact that it was funny detract from the value of its very sound practical advice on how to care for telescope optics. It was interesting to compare the differences in cleaning regimes between Martin and Barry.
After Martin’s talk we took the group photo. It is a great pity that not everyone pitched up for the group photograph as one likes to have everyone that attended on the photograph. Thanks to Auke’s efforts we also have a You Tube video of the behind the scenes efforts to get everyone setup for the photo. Go here to view the video.

ABSENT: André de Villiers, Martin Lyons, Rene Auras, Tyron Auras, Nicholas Kröner, Thomas Kröner, Nellie Brink, Dominique Brink.
The group photo was followed by the infamous Pub Quiz. Lynnette and I divided the attendees into six teams. This is quite a tricky operation. For starters, we know from past experience that separating parents from children or splitting couples are both big no-no’s. Then there is the really difficult task of trying to balance astronomy knowledge in the teams as well. Although the teams might have looked unbalanced numerically they were quite even as far as the knowledge levels were concerned. This is borne out by the fact that the final scores were quite close; team one (16), team two (20), team three (28), team four (22), team five (26) and team six (17). Each team had to choose a leader and Evan, in team two, was by far the most efficient team leader of the evening. After six rounds team three, consisting of Lynne, Juanita, Kiona, James, Lena, Leslie, Martin and Laura, was a clear winner. They had, in fact, maintained their lead since the end of round four.
After the team section we asked each team to nominate one representative to take part in the individual section. A further four rounds of questions followed and then we had a clear and very worthy individual winner in the person of Chris Forder. Congratulations Chris.
Strange how some people, even in a fun exercise like this, cannot resist resorting to looking up answers electronically or in a book. Some even erased answers and corrected them after the correct answer had been given thereby gaining an unfair advantage.
After the Pub Quiz there were still clouds around, but we decided to give it a go and Auke got the Constellation Exploration group (ConEx) together while I set up a telescope for the beginners. As luck would have it, just as we started, the clouds covered Venus, Saturn and eventually Mars too. We managed to discuss a few constellations and some objects of interests, but eventually people drifted off, as the clouds alternately advanced and retreated. For the most tenacious beginners there was eventually a fairly clear view of the Andromeda Galaxy (M31) before we all went to bed.
Nobody had done the observing challenge, so there were no certificates to hand out on Sunday morning. Lynnette and I were up at 08:00 to say goodbye to the early leavers and share a cup of coffee with them. By Sunday evening Lynnette and I, Auke, Barry and Miemie, John, Alan and Rose and Snorre were all that was left of the crowd and, as usual, we had a nice braai before setting op the telescopes to do some observing. Yes, you guessed correctly the weather cleared as soon as the SSP was over! On Monday afternoon, only Lynnette, Snorre, myself, Alan and Rose were left. On Tuesday morning we departed leaving the entire camp to Alan and Rose. Tersius and his team took down the tent on Tuesday afternoon and loaded up the tables and chairs, bringing down the final curtain on the 2016 Spring Southern Star Party.
A special word of thanks to our generous sponsors, because, without their help and support there is no way we could present a Southern Star Party.

In support of the efforts currently underway to document the history of the Royal Observatory a lot of historic material has been made available in digitized form by Auke Slotegraaf. While attempting to work my way through this formidable volume of information I came across the following in Royal Observatory, Cape of Good Hope, 1875 (iii).
“The “meridian mark” referred to in Table III, is on an undulation immediately to the east of the mountain called Blaauw Berg, and is situated some 13 miles north of the Observatory. It is a pillar built up to serve as a permanent meridian mark for the 10 feet Dolland’s Transit. The transit instrument is about 512 feet west of the meridian of the Transit-circle. The azimuth of the mark from the meridian of the Transit-circle, assumed in the determination of the azimuthal errors given in Table III, has been 2’ 40” west. It would appear that the assumed azimuth is too great by about 1”.3, and that the true azimuth of the mark is nearly 2’ 38”.7 west. The azimuthal errors derived from the position of the mark have not been used in the reductions, except for the approximate determinations of the clock error for time-ball purposes. The mark can only be well seen near noon on rather cloudy days; on bright, clear days it can only be observed soon after sunrise and near the time of sunset. The value of the mark as an indication of changes in the position of the Transit-circle, is not so great as it would be were observations possible at any hour of the day.”
So where was this meridian marker? After several e-mails between Auke Slotegraaf, Dr Ian Glass and I, it soon became clear that this specific object had not been seen by any members of the astronomical fraternity for many, many years. Ian produced correspondence dating back to 2012, in which a Mr. Seymour Currie, verified that that the object was in fact on his farm. The correspondence was conducted via the staff of Cape Nature at the Blaauwberg Nature Conservancy, and no mention was made of the farm’s name. Not knowing the farm’s name becomes a crucial point as the story develops.
I sent an e-mail to Mr. Currie who promptly phoned back. He had no objections to us coming to view, measure and photograph the meridian mark and he agreed to phone back again with instructions on how to get to his farm and an evaluation of how difficult it would be for us to get right up to the meridian mark. By Saturday morning, the 05th of December I had heard nothing from Mr. Currie and all telephone calls were answered by the dreaded voice message, “The subscriber you have dialled is not available ……”.
On the 05th a party consisting of Auke Slotegraaf, Chris Vermeulen, Dr. Ian Glass, Chris de Coning, Johan Brink, Kechil Kirkham, Dirk Rossouw and I, assembled at the Observatory. We were confident that, thanks to previous efforts by Ian and the help of Google Earth, we had the position pinned down and it looked as if there were useable access roads, but we were all anxious to hear from Mr. Currie.
The first task though, was to get up onto the roof of the Observatory building and try and see the meridian mark from there. Unfortunately the Eucalyptus trees that had been planted over the years successfully cut of, not only any possible view of the marker, but of the entire Blaauwberg. I had still not been unable to raise Mr. Curry on the phone so we decided to go with Google Earth and Google Maps and the coordinates of the marker. The route seemed pretty straight forward but Dirk several times expressed concern that we were venturing well of the beaten track and he had prior experience of the fact that Google did not take cognisance of fences and assorted farm gates in out of the way areas like this. In the absence of any communication from Mr. Currie we had little choice but to set off, guided by Google.
One section of the party, Auke, Kechil and Johan would stay behind and find a spot near the bird hide, at the northern extremity of the Observatory property, from which they hoped to observe the other section’s arrival at the marker. Chris dC had to first make a delivery and would join us later guided by Google. Chris V and Ian took the lead followed by myself and behind me Dirk. Somewhere on the N1 I lost sight of Dirk behind me but it turned out he had made a detour into Century City to refuel. I also lost sight of Chris V and Ian ahead of me but I had the Google turnoff from the N7, Frankdale Road, memorized so I was confident I would not get lost. I found the turnoff and after 1.3 km the tarred surface gave way to a track which became progressively worse, slowing me down to walking pace for long stretches. About 4.2 km from the N7, Zonnekus Road links up with Frankdale Road at a T-junction. There is a large, imposing, locked gate and, much to my surprise, parked on the other side of the gate were Chris V and Ian. While I was explaining to them how to get to where I was, Dirk pitched up, on my side of the gate. Chris V and Ian headed back to the N7 and Dirk and I waited. While we were waiting Chris dC arrived, also on the wrong side of the gate! More explanations and he also retraced his steps. After Chris V, Ian and Chris dC joined us Dirk once more voiced his concern that, although we were headed in the right direction, we might run into the Blaauwberg Nature Conservancy fences before reaching our target. Our cell phone signal had faded on us shortly after leaving the N7, so we were unable to update Google maps or try Mr. Curry again.
Off we went once again with Chris V and Ian in the lead, followed by Chris dC, then myself with Dirk bringing up the rear. Just over three km after leaving the gate, we encountered the gate and game fence of the Blaauwberg Nature Conservancy, as predicted by Dirk. Ian and I walked along the fence for quite a way trying to find higher ground on order to get a better view of the area where we thought the marker was and eventually we thought we had it. Unfortunately it was a case of so near and yet so far. After some debate we decided to call it a day and head home. I had to refuel as I did not have enough to get me home to Brackenfell and Chris dC very kindly offered to follow me to the filling station in Killarney in case I ran out of fuel completely. So we said our goodbyes and off we went.
After filling up in Killarney I parked the car and had a sandwich while going over the day’s events and checking that Mr. Currie had not tried to contact me. The more I thought about the day’s events the more I felt that Dirk had been right after all and we should have tackled this expedition from a farm called Blaauwberg on the northern slopes of the mountain. By now everyone else was well on their way back home or back to the Observatory, so I set of on my own. On the farm Blaauwberg I found that the owner was none other than Mr. Curry! It turned out that he and Willem Steenkamp had been very busy out in the veldt that morning planning the Battle of Blaauwberg Commemoration scheduled for the 09th January 2016.
After coffee we set off to the marker. Mr Curry and his wife took a quad-bike and I followed in their 4×4 all the way up to the marker, accompanied by their two magnificent Ridgebacks, racing along with the vehicles. The first kilometre after one leaves the farmyard is fine and can be attempted in any vehicle but the next just over one kilometre is uphill, sandy and riddled with mole tunnels. I would not venture up there in anything but a 4×4 vehicle.
Anyway, there the marker was and, after my hosts departed, I set about measuring and photographing. Both tasks were complicated by the fact that three sides of the marker were overgrown with very thorny bushes reaching almost to chest height. A section, which I think was added at a much later date than the original construction, has come off the top of the marker. The reason I think it is a later addition is that the cement looks quite different from that used in the construction of the marker and also, the removal does not seem in any way to have damaged the top of the marker. The marker is not, as stated in the reference at the end of this post, 14 feet (that’s over four m) high.
Mr Curry reports that up to about 10 years ago the military actually come round once a year and cleared away the brush around the marker but that no longer happens, as I can testify. It was not only the surrounding bush that made photography difficult but also the fact that the sun was fairly low in the west, which caused all sorts of complications with shadows. After finishing up I drove back to the homestead, reluctantly handed back the 4×4, said my goodbyes and headed home.
The Curries say that during military exercises with helicopters, it appears as if they fly to a point directly over the marker and then change course. Perhaps somebody could investigate this because it would be interesting to know if the marker is in fact used as a beacon, why and since when.
Dr Glass has also tracked down two more references to the meridian marker which seem to pinpoint its construction to August 1841.

Page 403: “Having obtained permission on the 10th of August, 1841, from the trustees of Dirk Gysbert Kotze, to erect a pillar on the Blaauwberg estate, on a hill south-west of his dwelling house, in the meridian of the transit room of the Royal Observatory, a party was told off for this service shortly after the return from the measurement of the Base. The pillar is a truncated pyramid 14 feet high, constructed of stone and lime masonry, cased with Roman cement.
By observation of the consecutive transits of circumpolar stars in the winter season made with the 10-feet transit instrument, the azimuth of the centre of the pillar is 179° 59’.57”, reckoning from the south round by the west; and by triangulation its distance is 68415 feet, or nearly 13 miles north of the transit instrument.”
Page 444: “The position of the pillar is on the undulation, immediately to the east of the mountain named Blaauw Berg, distant nearly 13 miles north from the Royal Observatory. The pillar was built to serve as a permanent meridian mark for the 10-feet transit instrument; also for obtaining the azimuths, by direct angular measurement of the trigonometric points, that are visible from the Observatory.”
Well there we were with ringside seats and a cloudy sky. Thin high level clouds which would not have been too much of a problem and thicker, discount fast moving low level clouds moving in ahead of a cold front. It was the low level lot that were a problem because a gap would hardly have opened up when it was promptly closed up again. Despite the adverse conditions I did manage to get several photographs of the partially eclipsed sun.
I have put the time each photograph was taken in the caption so that one gets some idea of the progression of the eclipse. All the photographs were taken with a Nikon D5100 camera mounted at prime focus on a Newtonian reflector (D=250), see ISO 400 and shutter speed = 0.25 seconds.
