V. Rumyantsev, N. Pit (CrAO), A. Pozanenko (IKI) report on behalf of larger
GRB follow-up collaboration:
We observed the field of the Swift GRB 110726A (Wolf et al., GCN 12196)
with AZT-11 telescope of CrAO between Jul. 26 (UT) 18:48 - 20:13. We do not
detect the afterglow (Schaefer et al., GCN 12197; Melandri et al., GCN
12198) . The photometry is based on the star used in GCN 12206 (Gorosabel
et al.) USNO B1.0 1460-02955684 (19 06 51.53 +56 04 41.2 ) assuming
R=18.06:
