At 22:39:02 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 240302 ***A*** (trigger=1218414). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 245.997, -15.470 which is
RA(J2000) = 16h 23m 59s
Dec(J2000) = -15d 28' 09"
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 ~750 counts/sec (15-350 keV), at ~1 sec after the trigger.
