V. Rumyantsev, N. Pit (CrAO), A. Pozanenko (IKI) report on behalf of larger
GRB follow-up collaboration:
We observed field of the Swift GRB 111103B (Grupe et al. GCN 12519) with
AZT-11 telescope of CrAO in R filter between Nov. 3 (UT) 16:12:05 -
17:00:21. We took several images of 180 exposure under unfavorable weather
conditions and mean seeing (FWHW) of about 4". We do not detect any source
within enhanced XRT position (Goad et al., GCN 12525). A photometry is
based on the USNO B1.0 nearby stars.
