At 16:14:21 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 230414 ***A*** (trigger=1164180). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 181.071, +53.127 which is
RA(J2000) = 12h 04m 17s
Dec(J2000) = +53d 07' 36"
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 ~757 counts/sec (15-350 keV), at ~5 sec after the trigger.
