January 7thNova in M33
For an exciting few minutes I thought I had found a new nova in M33.
A few checks showed that it had been discovered 2015/12/27 by E. Conseil
The total of M33 images I have now is 32 x 10 minutes.
Fainter regions are now starting to show well.
Possible nova spotted in M31
Several emails flew around the Internet to see if this was indeed a new nova.
After some time it became clear that this was a fresh outburst from M31 2015-10b.
This is unusual behaviour. Novae tend to flare up and then lie dormant for a very long time.
Traces of the nova were seen on older images. This compares Jan14 to Nov13:
