At 16:03:18 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 240303 ***A*** (trigger=1218498). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 299.547, +34.864 which is
RA(J2000) = 19h 58m 11s
Dec(J2000) = +34d 51' 51"
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 ~1101 counts/sec (15-350 keV), at ~0 sec after the trigger.
