OV Boo: possible ordinary superhumps

     Crimean Astrophys. Obs. team(O.Antonyuk), Franky Dubois, Domenico Licchelli,
Lew Cook, Osaka Kyoiku U. team, Pavol Dubovsky. Tamas Tordai, Shugarov's team
have reported new observations.
     The object was 13.5 V Mar. 27. The profiles of superhumps has been double-wave like
(but complex) modulations yet. However the superhumps have larger amplitudes (~0.4mag)
and we detected the longer period of ~0.0472 d than orbital one of 0.046258 d. Thus
these modulations are possible ordinary superhumps.
     Of course, further observations are strongly encouraged to detect period variations.
