At 02:20:36 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 240414 ***A*** (trigger=1221714). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 184.786, +56.727 which is
RA(J2000) = 12h 19m 09s
Dec(J2000) = +56d 43' 37"
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 ~2643 counts/sec (15-350 keV), at ~2 sec after the trigger.
