TITLE: GCN CIRCULAR NUMBER: 42238 SUBJECT: GRB 251014A: Swift detection of a possibly-short burst DATE: 25/10/14 00:42:58 GMT FROM: David Palmer at LANL <palmer@lanl.gov> E. Ambrosi (INAF-IASFPA), V. D'Elia (SSDC & INAF-OAR), R. Gupta (NASA GSFC) and D. M. Palmer (LANL) report on behalf of the Neil Gehrels Swift Observatory Team: At 00:28:30 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 251014A (trigger=1403878). Swift did not slew immediately due to an observation constraint. The BAT on-board calculated location is RA, Dec 111.732, +6.415 which is RA(J2000) = 07h 26m 56s Dec(J2000) = +06d 24' 54" with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve showed a single peak structure with a duration of about 1.5 sec. The peak count rate was ~3000 counts/sec (15-350 keV), at ~0 sec after the trigger. Due to a Moon observing constraint, Swift cannot slew to the BAT position until 21:52 UT on 2025 October 14. There will thus be no XRT or UVOT data for this trigger before this time. Burst Advocate for this burst is E. Ambrosi (elena.ambrosi AT inaf.it). 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/42238. --- To unsubscribe, open this link in a web browser: https://gcn.nasa.gov/unsubscribe/eyJhbGciOiJIUzI1NiJ9.eyJlbWFpbCI6InZzbmV0LW...
