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
