OV Boo: longer superhump period?

     Dubois's team (Franky Dubois, Ludwig Logie, Steve Rau, Siegfried Vanaverbeke),
Pavol A. Dubovsky, Maeda-san, Michael J. Cook, Osaka Kyoiku U. team, Tamas Tordai,
Lew Cook, Itoh-san, Denis Buczynski, Kyoto U. team have reported new observations.

     The object was 14.4 V tonight. OV Boo has shown stage B superhumps yet, and
the period may have become longer. The averaged period is 0.046756 (3) d between
March 27-31 and 0.046851 (4) d between April 1-3, respectively. However, the
superhumps may have been strongly contaminated not only by eclipses but some
kind of modulations (orbital motion?).
     Further observations are encouraged to clarify the superhump variations.
