Possible Supernova PSN J12215513+0428169 in M61

Possible Supernova PSN J12215513+0428169 was discovered on March 23, 2014 by the Lick Observatory Supernova Search (LOSS). Located at 2" west, 8" south of M61's nucleus, it was shining at a mere 19.0 mag at the time of its discovery and quickly fading below mag 20.0. Its type could not be determined yet.

As of late May 2014, it was found to be visible on two of the images but not detectable on a number of others, so it needs still confirmation. As dim as this one is, it may be a nova in M61.

.. more to come soon ..
