TITLE: GCN GRB OBSERVATION REPORT NUMBER: 2845 SUBJECT: GRB041211, Faulkes Telescope optical observation DATE: 04/12/13 18:46:04 GMT FROM: Cristiano Guidorzi at ARI,Liverpool JMU C. Guidorzi, A. Monfardini, C.J. Mottram (Liverpool John Moores University) and the Liverpool GRB team, on behalf of the larger Robonet consortium, report: "We obtained BVRI images of the SXC error box of GRB041211 detected by HETE-II (GCN 2839) with the 2-m Faulkes Telescope North on Maui, Hawaii. Observations started on December 11.615 UT, i.e. 3.2 hours after the GRB with an average seeing of 1.3 arcsec. The robotic GRB pipeline did not find any new objects with reference to USNOB, GSC2.3 and 2MASS catalogues. Time from GRB ExpTime Filter Limit Mag. (days) (s) ----------------------------------------------- 0.135 2x10 B 19.1 0.135 2x10 V 19.1 0.135 2x10 R 19.2 0.135 2x10 I 18.8 ----------------------------------------------- The above limit magnitudes have been derived using the calibration provided by Henden et al. (GCN 2844). After visual inspection of a 2 min R image taken soon after the automatic sequence reported above, we do not find any new candidate within the DSS limit. This message can be cited."
