f:id:kanataobslog:20091124222626p:image

We show the recent photometric results of optical transient in UGC 2773. The luminosity clearly show the brightening in BVRcIc-band. If this object is a luminous blue variable (LBV), the light curve would have decreased in the light curve. But, we confirm the increasing luminosity in the light curve. The light curve show the largest luminosity in the periods. We will continue the observations of OT in UGC 2773.
