I tried to find the SN last night (13th March) but conditions were poor, with lots of moisture in the air bringing the SQM reading down to little better than 20.00. Also I was fighting against the neighbours' security light.
Anyway, at 300x through the 20" dob, only the elongated patch of the galaxy was visible, with an obvious brighter centre. At 600x I began to get hints of the supernova, but with a FOV of around 8' the galaxy flew by and it was very tricky to keep it centred.
Eventually I could just make out briefly a second brighter area just east of the centre, with hints of its separation from the main body of the galaxy. Luckily I hadn't checked its position online beforehand, so the fact that the sketch matches its actual position gives me confidence I did see it. West is to the left. The star on the right side is, I believe, 14.5 magnitude. The sn was significantly fainter than this, even when the star was defocused, so I'd guess the sn was 15 mag or fainter. I've not been able to find any recent updates on it, so any further information welcome!
If I did imagine the whole thing and it's long gone, please keep it to yourself as it will make me look silly ;-)
