f:id:kanataobslog:20110731021947p:image

We performed photometric observations of optical transient in UGC 2773. This object was discovered on 2009 Aug 18.02 in UGC 2773. The light curves still show the similar luminosity to that at a year ago.

[] Type Ia SN 2011B : photometry at 200 days after maximum

f:id:kanataobslog:20110730210951p:image

We performed photometric observations of normal Type Ia SN 2011B at 200 days after maximum. The magnitude is well similar to that of SN 2003du at same phase except for I-band. The I-band magnitude may be contaminated by a background of the host galaxy. We will continue the photometric observations of this object.
