This image shows you a small-scaled galactic group positioned between gamma and zeta Leo that forms the root of Lion's Sickle. A most striking edge-on galaxy in center of group is NGC3190, and there are other surrounding galaxies of NGC3185, NGC3187, NGC3193, and so on. The members are distributed about 20 arc minutes in span and it's estimated that the group is about 70 million light years away.
On Mar 9, 2002, a supernova of 2002bo appeared in NGC3190 and lower picture can detect the supernova at a bit apart position from the center of galaxy.
This picture has taken six days before the supernova appeared.
