TITLE: GCN CIRCULAR NUMBER: 5864 SUBJECT: GRB061126: Optical afterglow observations from MIRO DATE: 06/11/26 20:36:58 GMT FROM: Kiran S Baliyan at Physical Research Lab, Ahmedabad,India K.S. Baliyan, S. Ganesh, UC Joshi (MIRO-PRL, Ahmedabad, India) report: We observed the field around position of the optical counterpart of GRB061126 (Swift Burst Alert Telescope (BAT) trigger number 240766) beginning about 8 hours after the burst. The 1296*1152 CCD mounted on the 1.2 M telescope of Mt Abu IR Observatory, operated by Physical Research Laboratory, Ahmedabad- India, was used to observe OT in RI bands and white light. Several images with exposure times 120 secs and 180 secs are taken. A visible inspection of the images shows a very faint source in I band and white light at the position reported by D. E. Vanden Berk, B. Sbarufatti, and S. D. Barthelmy (GCN 5856). Results of the detailed photometry will be reported later. The monitoring is on.
