by Taichi Kato 04 Aug '23

04 Aug '23

PNV J19030433-3102187: ordinary superhumps (WZ Sge) The most recent data by Itoh-san on Aug. 3 clearly showed ordinary superhumps. Long waiting time is consistent with the WZ Sge-type classification. (We have received observations from Josch Hambsch, which have not yet been analyzed. More details later).
