1-metre telescope of U.P. State Observatory and 2k x 2k CCD. The R magnitudes 
calibrated using stars A and D of Garnavich et al. (GCN #573) come out to be 
as follows:

 Mar 3.93 UT	20.53 +/- 0.05
 Mar 5.96 UT	21.18 +/- 0.05

	Using all R band observations reported so far the value of alpha
comes out to be 1.02 while excluding the R magnitude reported in #GCN 588,
alpha comes out to be 1.12 +/- 0.1. "
