sn03ed_i.jpg Discovered by Japanese amateur Koichi Itagaki. The host galaxy was identified in CBET 14 as "NGC 5303A" which NED identifies as "NGC 5303". Note that NGC 5303B is not very far away, and this was the sight of a possible (but debunked) supernova in 2000. Note: There is a star to the north west of the nucleus which is opposite to the side that the supernova is on. This one was a type II found on the rise. We have a DSS Photometry reference image made by Odd Trondal.  Icon generated from the discovery image.
