OR And observations from Tom Krajci Dear Colleagues, The VSNET Collaboration has received time-series photometry of OR And (still poorly studied VY Scl-type star) from Tom Krajci. The light curve suggests the presence of 3-hour modulations with a profile resembing that of superhumps in permanent superhumpers. The light curve also exhibit relatively strong QPO-like variations. The overall light curve resembles that of short-period novalike stars such as V592 Cas. OR And was briefly followed by the authors during the 1998 fading episode (reported by Timo Kinnunen), and the present high-state observation will eventually provide a long-range, multi-state photometric record of this object. Follow-up observations (for northern observers; after the main target of V585 Lyr) are encouraged. Regards, Taichi Kato VSNET Collaboration team
