Hi All
Mati Morel has generated a good chart for the SN now which is available through the AAVSO web site. I'd be wary of the mag 11.7 comparison star shown on the chart, it doesn't look quite right but the others appear fine. I visually observed the supernova again this morning and at Feb 17.756 UT it was mag 11.7.
Regards
Andrew Pearce
