Robin,
that is certainly encouraging for those of us contemplating SN hunting. M101 is a bright object regularly observed and that eluded discovery for almost 24 hrs. I’m close to having a 20″ Newt set up specifically for SN hunting. The biggest problem I will encounter I think will be a good, quick, and reliable automated method of checking images for suspects. If there any software writers interested in either a blink or image subtraction method or both I’d be interested in corresponding.
