Possible superoutburst of V1504 Cyg
G. Poyner reports that the SU UMa-type dwarf nova V1504 Cyg is undergoing
a bright outburst, presumably a superoutburst.
YYMMDD(UT) mag observer
971109.892 <150 (G. Poyner)
971111.894 <145 (G. Poyner)

The latest superoutburst of V1504 Cyg occurred in early August. If the
current outburst is confirmed to be a superoutburst, this system will be
confirmed to have one of the shortest supercycle lengths among "usual"
SU UMa-type dwarf novae.
