Pavol A. Dubovsky has kindly sent observations of OT_J163120.9+103134
= Catalina transient. Using the combined data set, we have obtained
a refined superhump period of 0.064102(8) d.
Timing analysis of superhumps showed a more complex picture.
During the first three nights, the period was almost constant
at 0.06398(2) d, then shifted to a longer period, followed by
a period decrease.
This complex behavior probably led to earlier somewhat contradicting
analysis of period variation.
Further analysis is in progress. We appreciate any further data
(and of course, please watch for a possible rebrightening).
