GCN Circular 1127
J. P. Halpern, N. Mirabal (Columbia), Chris Burke, & D. L. DePoy (Ohio State), report on behalf of the MDM Observatory GRB follow-up team: "Using the MDM 2.4m, we obtained 15 minutes of exposure in the I band centered at Oct. 31.21 UT, 22.5 hours after the burst. All of the 2.1' radius refined BeppoSAX error circle (in 't Zand et al., GCN #1123) was covered. A follow-up observation was performed on Nov. 1.22 UT, with 15 minutes of exposure. Conditions were not photometric, and these images have not been calibrated. However, no afterglow candidate has been found to a limit approximately 1 mag fainter than the POSS-II IVN plate, or I_c > 20.5.
