WZ Sge: 12-th rebrightening! Dear Colleagues, The most recent data from D. Starkey clearly shows that the 12-th rebrightening has taken place, as suggested by the Kyoto observation! Since the course of the 11-th rebrightening and the subsequent fading was different from those of the earlier ones, observers are strongly requested to observe the behavior following the latest change. More detailed analysis is in progress. Regards, Taichi Kato VSNET Collaboration team
