V. Rumyantsev (CrAO), A. Volnova (SAI MSU), E. Elunko (ISTP), A. Pozanenko
(IKI), on behalf of larger GRB follow up collaboration report:
We observed the 110328A / Swift J164449.3+573451 (Cummings et al., GCN
11823) with Shajn telescope of CrAO observatory and AZT-33IK telescope of
Sayan observatory (Mondy) . Several series were taken on March 31, April 1
and 3. In each epoch of our observations we clearly observed the optical
counterpart (Cenko et al., GCN 11827, Leloudas et al., GCN 11830, Volnova et
al., GCN 11837). The photometry is based on the USNO B1.0 star 1476-0321081
(16 45 07.13 +57 36 03.4) assuming R=19.38. The first column represents the
time since first Swift trigger (Cummings et al., GCN 11823).
