TITLE: GCN CIRCULAR NUMBER: 13609 SUBJECT: GRB 120802A: optical observations DATE: 12/08/07 23:37:03 GMT FROM: Alexei Pozanenko at IKI, Moscow L. Elenin (KIAM), A. Volnova (SAI MSU), I. Molotov (KIAM), A. Pozanenko (IKI) report on behalf of larger GRB follow-up collaboration: We observed the field of GRB 120802A (Holland et al., GCN 13555) with 0.45-m telescope ?f ISON-NM observatory starting on Aug. 02 (UT) 08:13:18 (Elenin et al., GCN 13556). We took several unfiltered images of 30 s and 60 s exposures starting on Aug. 02, (UT) 08:13:18. At the edge of the enhanced by UVOT field astrometry XRT error circle (http://www.swift.ac.uk/xrt_positions/529486) we marginally detect a source in coordinates 02:59:22.35 +13:46:07.2 (uncertainty of about 0.3 arsces in both coordinates). A preliminary photometry of co-added frames is based on the USNO-B1.0 (R2) nearby stars is following: T_start, T0+, Exposure, Object, (UT) mid, d (s) 08:13:18 0.06905 6360 21.2+/-0.6 We suggest the source might be an optical afterglow of GRB 120802A, however at that time we cannot confirm the fading origin of the source.
