TITLE: GCN GRB OBSERVATION REPORT NUMBER: 3467 SUBJECT: GRB 050525 - Very Bright, Not Short DATE: 05/05/25 02:14:26 GMT FROM: Craig Markwardt at NASA/GSFC/UMD C. Markwardt (GSFC/UMD), S. Barthelmy (NASA/GSFC), L. Barbier (GSFC), J. Cummings (GSFC/NRC), E. Fenimore (LANL), N. Gehrels (GSFC), D. Hullinger (UMD), H. Krimm (GSFC/USRA), D. Palmer (LANL), A. Parsons (GSFC), T. Sakamoto (GSFC/NRC), G. Sato (ISAS), M. Suzuki (Saitama), J. Tueller (GSFC) on behalf of the Swift-BAT team: GRB 050525 (Swift trigger 130088) was observed by Swift BAT. At the present, only rate data are available. This initial data indicate that the burst was very intense (peak rate of 80,000 ct/s above background). The light curve consists of at least two ragged peaks, with a total duration of approximately 10 seconds (15 - 200 keV). Thus, this is not a short burst as initially speculated (Band et al. GCN #3466), but it is one of the brightest bursts of the year.
