Possible supernova PSN J02331624+1915252
is present in multiple images obtained with the quadruple 14-cm ASAS-SN "Brutus" telescope in Haleakala, Hawaii. Due to severe contamination from a relatively nearby bright star, our software did not flag this event as a possible supernova, but it is present in subtracted images as early as UT 2015-06-27.6 (V~15.5), peaking at V~15.3 on UT 2015-07-23.6 (see
the ASAS-SN
light curve here; due the contamination, the light curve is significantly noisier
than usual).
