OV Boo: stage A-B transition?

     Tamas Tordai, Tonny Vanmunster, Lew Cook, Denis Buczynski, Kasai-san,
Maeda-san and Kyoto U. team have reported new observations.
     The object is 13.9 V now, and has shown sigle-wave modulations for 1 day.
The period is 0.04670(1) d and shorter than the period of 0. 04734 (1) d on
March 25-26. These periods suggests that the stage A-B transition occurred
on March 27. However, the light curve is contaminated by the deep eclipses
and it is difficult to detect the accurate periods by using lacking data.
     Further observations are needed to update the periods.
