by Taichi Kato 01 Mar '22

01 Mar '22

SX LMi: early stage transition Itoh-san, Kiyota-san, Kyoto U. team, Kubodera-san, Imamura-san and Filipp Romanov have reported observations. There was a clear stage transition on Feb. 23. This looks like stage B-C transition, and if it is the case, the duration of stage B was short compared to other SU UMa stars with similar orbital periods.
