TITLE: GCN GRB OBSERVATION REPORT NUMBER: 3020 SUBJECT: GRB050209: TAROT optical observations DATE: 05/02/11 03:57:13 GMT FROM: Michel Boer at Obs Haute Prov. Alain Klotz (CESR-OHP), and Michel Boer, (OHP) on behalf of the TAROT team report: "We imaged the entire field of GRB 050209 with the TAROT robotic telescope located at the Calern observatory, France. Observations started 26 seconds after the receipt of the GCN notice, i.e. approx. 2h25 after the event. The position was at an elevation of 22 degrees above the western horizon. No new source was detected after a comparison with the USNO A2-0 catalogue. From a frame to frame study no decaying source was found. We co-added 84 30s images: we reach a limiting R magnitude of 19.2. A summary of the data, as well as TAROT images can be found at the following URL: http://www.cesr.fr/~klotz/grb050209/ " This message is citable.
