V402 And superhump period update Preliminary analysis of the subsequent data taken at Ouda Station, Kyoto Univiersity, combined with Jochen Pietz's data, seems to prefer a shorter period. The strongest periodicity up to now is at 0.0634 d, with a smaller degree of possibility around 0.0661 d. More observations are clearly needed to pin down the superhump period. Further progress will be announced in vsnet-campaign-dn list. Regards, Taichi Kato VSNET Collaboration team
