At 16:58:30 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 240303 ***A*** (trigger=1218505). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 228.560, -56.980 which is
RA(J2000) = 15h 14m 14s
Dec(J2000) = -56d 58' 46"
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 ~1070 counts/sec (15-350 keV), at ~0 sec after the trigger.
