VW CrB: long superoutburst
After some rainy/cloudy nights in Kyoto, we again started a run
of VW CrB (after AL Com, very faint now) and confirmed that the
object is still bright at about R=15.2mag. The current outburst
was first reported on June 18 by M. Simonsen, and to date, no
dip or rapid decline was confirmed. The superoutburst hence lasts
for near three weeks, quite longer than that of ordinary SU UMa
stars. In the last observation at Kyoto, we detected double-peaked
periodic humps, so time-series observations are urgently encouraged
to study the current status of this object.
