V503 Cyg : positive superhumps?

  Osaka Kyoiku Univ. team have reported further observations. And we also
took observations of this object. According to data after the decline,
0.080311 (15) d is obtained. This implies that the obseved variations are
not negative superhumps, but rather positive superhumps. However, the 
yielded period is a little shorter than that in the past paper.
 The next (maybe normal) outburst will occur in the near  futher since
the interval of this object is short. It is interesting matter how this
superhumps will develop when the next outburst starts.

 Further observations are required!
