[vsnet-alert 5244] SN 2000dj too rapid fading?

SN 2000dj too rapid fading?

  As reminded by Yamaoka-san, the reported SN 2000dj may not be a supernova.
If the observation by Sostero is correct, the reported fading of 2.8 mag
in 1.6 d is exceptional for a supernova!  The object may be a foreground
recurrent eruptive object.  Further observations and search for old
materials are highly encouraged.  The speed of decline may be acceptable
for a normal outburst of an SU UMa-type dwarf nova.
