VW CrB superhumps Dear Colleagues, The Kyoto team (observers: M. Uemura and R. Ishioka) has naturally been following VW CrB during the current superoutburst. On July 26, fully grown superhumps were clearly detected with an amplitude of 0.3-0.4 mag. The nightly data have covered nearly three superhump cycles. The statistics is already much better than the 1997 observation, and we hope we will be able to obtain the accurate superhump period and its change. The measured superhump period from the preliminary analysis is slightly shorter than the literature value. This needs to be confirmed with further analysis and observation. There is no evidence of secondary superhump maxima yet. PS. The announcement of this observation has been delayed because we already had a fairly good coverage of the 2001 superoutburst. The quality of the present observation, however, likely surpasses those of the past observations. Please turn your telescope to the promising VW CrB superoutburst. Regards, Taichi Kato VSNET Collaboration team
