WZ Sge: superhump period update Dear Colleagues, We have receieved new data from the RIT observatory team (M. Richmond, S. Davis, T. Davis), D. Starkey and partly analyzed the Kyoto Aug. 8 run. The general fading has almost stopped. We have updated the superhump period as 0.057231(30) d, by a least-squares fitting, rather than the PDM analysis. As the baseline becomes longer, the analysis tends to give a longer period than the 'canonical' period obtained during the 1978 superoutburst. The profile of superhumps strongly vary with time. Further observations are strongly encouraged! Regards, Taichi Kato VSNET Collaboration team
