This nova was at mag 6 when it was discovered 3 days ago and has brightened every day and was about mag 3.6 earlier today ( Dec 5th). Near beta Cen, it is easy to find but you need to go out at about 3:30 am to see it.
On Monday, December 02, John Seach based at Chatsworth Island in NSW (Australia) discovered a nova in Centaurus. Located less than 2° from beta Centauri, the nova has brightened to become a naked-eye target. The Shallow Sky Section of ASSA has a finder chart and more information. At mag 6 when it was discovered it has brightened first to around mag 4 and then appeared to be fading. Recent observations, however, seem to indicate that it may still be brightening and it was at around mag 3.6 on 11/12/13.
