TITLE: GCN GRB OBSERVATION REPORT NUMBER: 2972 SUBJECT: GRB050124: Swift-BAT position of a double-peaked burst DATE: 05/01/24 13:08:18 GMT FROM: Craig Markwardt at NASA/GSFC/UMD C. Markwardt (GSFC/UMD), S. Barthelmy, L. Barbier (GSFC), J. Cummings (GSFC), E. Fenimore (LANL), N. Gehrels (GSFC), D. Hullinger (GSFC/UMD), H. Krimm (GSFC/USRA), K. McLean (LANL), T. McMahon (Langston U.), D. Palmer (LANL), A. Parsons (GSFC), G. Sato (ISAS), P. Schady (MSSL), T. Sakamoto (GSFC), M. Suzuki (Saitama), J. Tueller (GSFC) on behalf of the Swift-BAT team: At 11:30:03 UT, the Swift Burst Alert Telescope (BAT) triggered and located on-board GRB050124. The spacecraft did not autonomously slew to the burst because automatic operations were disabled for weekend operations. The spacecraft will be repointed via a Target of Opportunity command. The BAT on-board calculated location is RA,Dec 192.879, +13.026 (J2000) with an uncertainty of 6 arcmin (radius, 3-sigma, including a systematic uncertainty). This is a high significance burst. The structure of the burst is double-peaked with a duration of ~4 seconds.
