At 05:59:58 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 240302 ***A*** (trigger=1218302). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 83.886, +21.875 which is
RA(J2000) = 05h 35m 33s
Dec(J2000) = +21d 52' 30"
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 ~921 counts/sec (15-350 keV), at ~3 sec after the trigger.
