TITLE: GCN GRB OBSERVATION REPORT NUMBER: 4741 SUBJECT: GRB060211.7: MASTER_optical_observation under the snow DATE: 06/02/11 17:34:27 GMT FROM: Vladimir Lipunov at Moscow State U/Krylov Obs V. Lipunov, V.Kornilov, D.Kuvshinov, N.Tyurina, A.Belinski, E.Gorbovskoy, A.Krylov, G.Borisov, A.Sankovich, G.Antipov, V.Vladimirov M.Sinitsin, P.Gritsyk Sternberg Astronomical Institute, Moscow Union 'Optic' MASTER robotic system (http://observ.pereplet.ru) responded to GRB060211.7 (GRB_TIME is 2006-02-11 15:55:14.76). The first image was at 2006-02-11 15:59:57 UT, 00:04:42.24 after the GRB time (after opening the roof under snow). The unfiltered image is calibrated relative to USNO A2.0 (0.8 R + 0.2 B). The robot not find OT-candidate in error box brighter then 14.5 (s/n=3). The reduction is continuing. This work is supported by RFFI 04-02-16411 grant. This message can be cited.
