D. Grennan, Raheny Observatory, Dublin, Ireland reports that this possible supernova was seen on an 10 x 1 minute stack of unfiltered frames (L.M. +20.1). These images were taken with a 0.36-m SCT and SBIG ST8 CCD. Astrometry returned the following J2000 coordinates, RA= 22:41:51.79 (+/-0.1") Dec= +34:58:06.7 (+/-0.1"). The unfiltered magnitude estimate is +16.5U. This image is available at; http://www.webtreatz.com/images/J22415183+3458074.jpg
