V368 Per: stage C superhump

     Roger Pickard, Crimean Astrophys. Obs. team (Sosnovski, A.,
Babina, Yu., Baklanov, A., Pavlenko, E.  ), Ian Miller and Pavol A.
Dubovsky have reported further observations.
     The object has shown stage C superhumps from Oct. 2. The
superhump periods of stage B and C are 0.07913 (1) d and
0.07872 (8) d, respectively. The Pdot during the stage B is
11.6 (7.7) * 10^(-5). According to our O-C diagram, we can
see the stage A-like trend before the stage B. However, the
estimated period by the PDM method was shorter than stage B.
It seems to be caused by the short run (only 3 humps).
     The last observation was performed on Oct. 4. So the object
may be already faded.
