TITLE: GCN CIRCULAR NUMBER: 36108 SUBJECT: GRB 240415A: Swift detection of a burst DATE: 24/04/15 07:14:36 GMT FROM: David Palmer at LANL <palmer@lanl.gov> M. J. Moss (GSFC), K. L. Page (U Leicester) and D. M. Palmer (LANL) report on behalf of the Neil Gehrels Swift Observatory Team: At 06:26:53 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 240415A (trigger=1221874). Due to a telemetry gap, only limited information is available, specifically the detector plane histogram and associated metadata. Ground analysis of this histogram finds a source at RA, Dec 129.128, +73.169 which is RA(J2000) = 08h 36m 31s Dec(J2000) = +73d 10' 08" The metadata indicates a trigger duration of 1 s, which does not distinguish between a short or a long burst. We note that this trigger time and position is consistent with Fermi GBM's detection of GRB 240415A (GCN 36107). Burst Advocate for this burst is M. J. Moss (mikejmoss3 AT gmail.com). 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/36108. --- To unsubscribe, open this link in a web browser: https://gcn.nasa.gov/unsubscribe/eyJhbGciOiJIUzI1NiJ9.eyJlbWFpbCI6InZzbmV0LW...
