[vsnet-campaign-dn 971] VW CrB: long superoutburst

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.

Regards,
Makoto Uemura
