TITLE: GCN CIRCULAR NUMBER: 17121 SUBJECT: GRB 141130A: Mondy optical observations DATE: 14/12/01 00:28:33 GMT FROM: Alexei Pozanenko at IKI, Moscow E. Mazaeva (IKI), E. Klunko (ISTP), I. Korobtsev (ISTP), M. Eselevich (ISTP), A. Volnova (IKI), A. Pozanenko (IKI) report on behalf of larger GRB follow-up collaboration: We observed the field of GRB 141130A (Vargas et al., GCN 17120) with AZT-33IK telescope of Sayan observatory (Mondy) Nov., 30 starting on (UT) 23:15:04, i.e 248 s after burst trigger. In first images of 10 s exposure we clearly detect fading object in coordinates of the OT candidate reported in (Vargas et al., GCN 17120). The object is absent in DSS2 and we thus confirm optical afterglow of GRB 141130A. The afterglow has faded from R = 18.5 +/- 0.14 at 258 s after burst trigger to R = 19.2 +/- 0.2 at 800 s after burst trigger. The photometry is stil preiminary and based on nearby USNO-B1.0 stars.
