SDSSp_J173008.38+624754.7: superhump period revised
We combined the Kyoto team data on October 23 with the data
kindly sent by T. Vanmunster and A. Oksanen, and performed period
analysis. We obtained a period of 0.07898 (13) d which is somewhat
shorter than previously reported using only October 22 observations.
The average profile of humps is single-peaked, very similar to
typical superhumps with an amplitude of 0.2mag. As reported by
T. Vanmunster, the light curve of the earliest phase which we have
on October 19/20 also shows a hump with probable single peak.
Our period analysis imply that the phase of its hump peak may however
be different from that on October 22-23. This may indicate period
changes of the superhump period.
Futrher observations are encouraged.
Regards,
Makoto Uemura
