TITLE: GCN CIRCULAR NUMBER: 16012 SUBJECT: GRB 140320C: Mondy optical observations DATE: 14/03/20 20:31:29 GMT FROM: Alexei Pozanenko at IKI, Moscow A.Volnova (IKI), E. Klunko (ISTP), I. Korobtsev (ISTP), M. Eselevich (ISTP), A. Pozanenko (IKI) report on behalf of larger GRB follow-up collaboration: We observed the field of GRB 140320C (Mereghetti et al., GCN 16007) with AZT-33IK telescope of Mondy observatory starting on Mar. 20 (UT) 15:12:44. We obtained several images of 120 s exposure in R-filter. Within entire INTEGRAL error circle we identified sources which are not presented in the DSS2(R) image: N RA(J2000) Dec. (J2000) 1. 08 57 55.04 +71 13 36.5 2. 08 57 16.68 +71 10 10.6 3. 08 57 34.11 +71 11 55.0 (Uncertainty of all coordinates are 1 arcsec.) However, our images are more deep than DSS2(R), down to a limiting magnitude R~21, and at present time we cannot determine whether the sources are fading.
