TITLE: GCN CIRCULAR NUMBER: 37032 SUBJECT: GRB 240805A: Swift detection of a burst DATE: 24/08/05 02:26:17 GMT FROM: David Palmer at LANL <palmer@lanl.gov> S. Dichiara (PSU), R. Gupta (NASA GSFC) and D. M. Palmer (LANL) report on behalf of the Neil Gehrels Swift Observatory Team: At 02:02:22 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 240805A (trigger=1246907). Swift slewed immediately to the burst but the observations was cut short almost immediately after the end of slew due to an observing constraint. The BAT on-board calculated location is RA, Dec 190.911, -53.622 which is RA(J2000) = +12h 43m 39s Dec(J2000) = -53d 37' 17" with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve is not immediately available. However, the original BAT trigger shows an excess of 3.3k counts in 1.024 s (25-100 keV) at the time of the trigger. The XRT and UVOT observations were only a few seconds long, so X-ray and optical positions and lightcurves will not be available until the GRB comes out of constraint around 02:58 UT. Burst Advocate for this burst is S. Dichiara (sbd5667 AT psu.edu). Please contact the BA by email if you require additional information regarding Swift followup of this burst. In extremely urgent cases, after trying the Burst Advocate, you can contact the Swift PI by phone (see Swift TOO web site for information: http://www.swift.psu.edu/) View this GCN Circular online at https://gcn.nasa.gov/circulars/37032. --- To unsubscribe, open this link in a web browser: https://gcn.nasa.gov/unsubscribe/eyJhbGciOiJIUzI1NiJ9.eyJlbWFpbCI6InZzbmV0LW...
