■ [Possible supernova] Optical transient in UGC 2773 ; update
we update the light curve of anomalous optical transient in UGC 2773.
We update the light curve of sub-luminous Type Ia SN 2009im. The I-band luminosity of this object undergo rebrightening. The secondary peak of I-band for a sub-luminous SN Ia is weaker than normal Type Ia. Fainter SNe Ia would be expected the earlier and fainter secondary maximum of I-band.
