TITLE: GCN CIRCULAR NUMBER: 35530 SUBJECT: GRB 240112C: SAO RAS optical observations DATE: 24/01/13 04:58:59 GMT FROM: Moskvitin Alexander at SAO RAS <mosk@sao.ru> A. S. Moskvitin and O. A. Maslennikova (SAO RAS) report on behalf of the GRB follow-up team. We observed the field of Swift GRB 240112C (Eyles-Ferris et al., GCN #35522) with the 1-m telescope of SAO RAS equipped with the CCD photometer. We obtained 21 x 60 sec. images in Rc band on January 13, 03:00:16--03:34:31 UT (t_mid - T0 = 0.40277 days) under mediocre weather conditions. We did not detect any significant source at the OT position down to the limiting magnitude R_lim = 21.1 (based on R2 magnitudes of nearby USNO-B1 stars).
