TITLE: GCN CIRCULAR NUMBER: 11402 SUBJECT: GRB 101112A: optical observations DATE: 10/11/13 18:23:26 GMT FROM: Alexei Pozanenko at IKI, Moscow A. Pozanenko (IKI), M. Ibrahimov (MAO), A. Volnova (SAI MSU), B. Satovski (Astrotel) report on behalf of larger GRB follow-up collaboration: We observed the field of INTEGRAL GRB 101112A (Gotz et al., GCN 11396) with AZT-22 telescope of Maidanak observatory between Nov. 13 (UT) 13:37:57 -- 14:05:56.Totally we obtained 6 images of 300 s exposure in R filter. The afterglow (Guidorzi et al. GCN 11397; A. de Ugarte Postigo et al. GCN 11398) is not visible on single images, and upper limit of the single image is R~20m at Nov.13 (UT) 13:40. The result above is preliminary. We thank Olga Ezhkova for performing the observations and for support.
