OU Vir: updated superhump period Dear Colleagues, We have received new data sets from Nakajima-san and Berto Monard. The superhumps still persist, and now (early May 9) overlap with the eclipses. The beat phenomenon is clearly present. The mean depth of eclipses on early May 9 was 0.5-0.6 mag. All the observed superhump times up to May 9 are well expressed by a single period of 0.07505 d, which confirms the period identification in [vsnet-campaign-dn 3640]. There is marginal evidence of a period decrease, which needs to be confirmed by further observations (due to the presence of overlapping eclipses, the period derivative is more difficult to determine than in non-eclipsing SU UMa stars). Regards, Taichi Kato VSNET Collaboration team
