f:id:kanataobslog:20090908160950p:image

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.
