A Supernova has been discovered in M100 (ngc4321) in Coma Beranices.discovered at about 17th mag it is now down to 14.5 and getting brighter, it could get as bright as 12.5 or better. This would be a good target for CCD imagers or medium to large scopes.
The Moon will interfer with observations for the next week or so but by that time the Supernova should be at peak brightness.
