VW CrB: double-peaked superhumps
Our observation on July 4 shows the superoutburst is still ongoing.
The decline rate from July 2 to 4 is 0.05mag/d.
In the light curve on July 4, we can see two clear humps with an
amplitude of 0.2mag. Their profile looks double-peaked one which
is sometimes observed in the late phase of superoutbursts.
Since we cannot see clear humps in the light curve on July 2,
we may detect re-growth of superhumps or late superhumps.
Regards,
Makoto Uemura, Ryoko Ishioka, and Taichi Kato
