[vsnet-campaign-dn 555] CP Dra
D. Buczynski has kindly sent us his data taken on February 24/25.
The data includes two superhumps with an amplitude of ~0.3mag.
The Kyoto team also performed time-series photometry on February 27.
The data shows a clear hump with 0.35mag amplitude.
The object has begun declining with a rate of ~0.12 mag/day.
It is interesting that we can see 0.2mag brightening between
February 24 and 25 in the Kyoto observations.
In conjunction with changing decline rate since February 25,
this may be because of the beat phenomenon or because the supermaximum
lies around February 25.0 (UT). Follow-up observations during this
superoutburst will reveal the current status.
Using the 1809 photometric points which the VSNET collaboration team
obtains, we performed the PDM period analysis and obtained the
best candidate of the period of 0.08491 +/- 0.00009 day.
