We have performed the photometric observations of the optical transient in UGC 2773 since Sep. 1 in 2009. In first year, the light curve exhibits the slowly rising time. It takes 150 days of increase up to ~16 from ~17 mag in each band with a complex short time-scale fluctuation. The color exhibits a rough constant value of V-R ~ 0.6 -- 0.7. On the other hand, in the second year, the color exhibits the rapid changing into the blue color. The variability width in V-R is roughly estimated to be 0.5 mag. The temporal color variability indicates that this object might form a dust with a small opacity.
