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.
