Stargazing visit to Leeuwenboschfontein: Monday 26th of December 2016 to Sunday 01st January 2017.

The day after Christmas we (Lynnette, Snorre and I) arrived at Leeuwenboschfontein just before lunch. We were followed later in the week by Iain Finlay – Willem stayed at home keeping their cats, Tiger and Aimé, company. Rob Bark with his wife Michelle and daughter Victoria were next in, followed, eventually, by Paul Kruger, with his famous breakfast. Dave, Spiro and Sharon were due to fly in from up north but eventually drove down due to thundery weather over the central parts of the country.  Martin Lyons had plans to fly in as well but gave up on that idea as the altitude, heat and short runway made it unsafe for the plane he was going to use. Auke could not make it either because of last minute complications.

I have to sit here all morning and wait for them to finish so that we can get going and go to Leeuwenboschfontein.

Monday evening was fine, Tuesday evening was completely clouded over and Wednesday evening was very windy in the early evening with a fair amount of cloud that cleared after midnight. Thursday night was a repeat of Wednesday and Friday was more of the same. Saturday was a near-perfect night to round off the weekend.

One thing that is a problem at Leeuwenbosch is the lighting along the entrance road and in the garden between the guest houses.  They are all these horrible round white things that distribute light in all directions. Some sort of a cover that prevents light from escaping upward and horizontally, would solve the problem and the use of cooler bulbs would also help. I temporarily solved the problem by taking the bulbs out as soon as it looked as if all the folks in the houses had gone to bed and then replaced them when I was done observing. Johan Roux, however, has shown me where the light switches for these lights are and it is now a case of flicking two switches and seeing conditions around the guest houses and new chalets will improve by at least 200%.

The camp, however, was a bigger problem this time around. Because it was the holiday season and specifically the New Year’s weekend, the camp was full of revellers who switched on all possible lights including that infernal spotlight on the mast in the middle of the camp. Why get tipsy in the dark, after all? The light spill from this lot even affected the seeing down in the telescope area next to the runway, almost a kilometre away.

At least these light pollution problems will not be a problem during the SSP because we have Johan’s permission to switch everything off for that weekend.

On the subject of light pollution, I recorded a set of dark sky readings for those of the readers who might be interested.

I also recorded some weather data, using Hans van der Merwe’s clever data logger. Here are some results that might interest amateur astronomers.
