CP Dra superhump growth: the early stage of superoutburst!
Further to [vsnet-alert 5708], the analysis of the subsequent data
(observations by R. Ishioka and H. Iwamatsu et al.) has clearly demonstrated
the growth of superhump, as we had observed in the recent successful UV Per
and TV Crv campaigns. The amplitude of superhumps has become as large as
0.2 mag during the half of the run. This clearly indicates we have witnessed
the very important growing stage of superhumps!
The period analysis using the all data has yielded a preliminary period
of 0.078 d, which is significantly longer than that reported by Tonny
Vanmunster. Although this difference may be attributable to the still
unstable superhump periodicity or variable waveform, the exact value of
the superhump period needs to be confirmed. More observations of this
favorably located (for northern observers) new SU UMa-type dwarf nova is
very strongly encouraged. The target indeed deserves one of top-priority
targets of the VSNET Collaboration team!
