At 00:28:30 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 251014 ***A*** (trigger=1403878). Swift slewed immediately to the burst.
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 [**double-peaked**]
structure with a duration of about TTT sec. The peak count rate
was ~3226 counts/sec (15-350 keV), at ~0 sec after the trigger.
