Thanks again both of you for your help on this one!

The only mags I can find are on Bright Supernova page which need careful checking as some are undefined as to filter, if used. The "m14.8" appears to be a red magnitude and visual will be typically 1 mag fainter :o
This SN appears to be about mag 14.8. Rich (RLTYS)

Rich - I checked the images posted, some with mag estimates
Not sure I agree. Can you tell me where on the Bright Supernova homepage you found mag estimates for this SN? I've not been able to locate them.

Sure, just click on the Supernova in the list that you are interested in and when the information about the nova comes up (about three or four lines) click on the hyperlink for magnitude and that will bring up a list of those mag. that have been reported.

I think this is the SN to look for rather than 2013am in M65 which I think is much fainter and now fading :o

Indeed, it is readily observable with 18 inches and I would dare say under optimum conditions it might be doable with less than 15 inches. Last Friday evening we have had quite steady seeing, and the nucleus and supernova were quite distinct. I was surprised by the brightness of the galaxy, I got carried away from the CCD images on this thread and I expected a much fainter galaxy.
...just how close the SN is the galaxy core; seeing was pretty soft with a cool breeze blowing, but I was able to get a clear split in averted vision in my 18-inch with the 5mm XW (no paracorr, for 380X...-George
I include the central part of my sketch which shows the SN to the right (south) of the galaxy core (I include only part of the sketch as the low resolution allowed at CN makes the SN inseparable). The sketch was made with my 18" and a 7mm TV Nagler at 294X.
