image Discovered by Tom Boles (UK).   This one needs a web page just to hold it's history.   This object was initially classified as an LBV, but it started to get very bright after that observation.   After getting up to Mag 14 (MUCH brighter than an LBV should get in a galaxy with a redshift Z of 0.0036) another spectrum was taken, and it was reclassifed as a type IIn.   It was reported more than once.   We have a Photometry reference image made by Odd Trondal.   This supernova is in the Constellation Ursa Major.
