TITLE: GCN CIRCULAR NUMBER: 18767 SUBJECT: V404Cyg Swift Trigger 668097: AbAO optical observations DATE: 15/12/30 10:31:22 GMT FROM: Alexei Pozanenko at IKI, Moscow E. Mazaeva (IKI), R. Inasaridze (AbAO), A. Volnova (IKI), V. Ayvazian (AbAO), I. Molotov (KIAM), A. Pozanenko (IKI) report on behalf of larger GRB follow-up collaboration: We observed V404 Cyg after Swift BAT trigger 668097 (Barthelmy et al., GCN 18716) with AS-32 (0.7m) telescope of Abastumani Observatory. Observations started on Dec., 28 (UT) 16:19:10. We obtained several unfiltered images of 60 s exposure. The source has a flare during our observations, the maximal brightness of the source during our observations is 15.5m at (UT) 16:22:39. It is also apparent that we observed only a small episode of new flaring activity of V404 Cyg. Preliminary light curve of the V404 Cyg can be found in http://grb.rssi.ru/V404_Cyg/v404Cyg_AAO_20151228_lc.png Photometry is based on following USNO-B1.0 stars USNO-B.1_id R2 1238-0434779 13.52 1238-0434864 14.12
