(IKI) on behalf of larger GRB follow up collaboration report:
We observed the field of GRB 110503A (Stamatikos et al. GCN 11991) with
Shajn telescope of CrAO observatory on May. 3 starting (UT) 23:56. We took
several frames with exposure of 60s in R-band. The afterglow (Stamatikos et
al. GCN 11991) is well detected in each single frame. A preliminary
photometry is based on the USNO B1.0 star 1421-0227752 (08:51:10.01
+52:11:04.75) assuming R=16.819 (Updike et al. GCN 12001):
