CI UMa superuhump period

   Crimean Astrophys. team (K. Antonyuk, N. Pit, E.Pavlenko and
A.Sosnovskij) reported observations of the current superoutburst.
It seems that a period of 0.06245(2) d expresses the observation.
Pdot appears to be positive, but the conclusion is not definite
due to the gap in the observation.  During the late stage of
the superoutburst, we could see a period of 0.06137(1) d,
which may be too long for the orbital period and too short
for stage C superhumps.  Further observations are needed.
