At 04:13:42 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 240305 ***A*** (trigger=1218701). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 229.705, -57.343 which is
RA(J2000) = 15h 18m 49s
Dec(J2000) = -57d 20' 32"
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 ~1511 counts/sec (15-350 keV), at ~2 sec after the trigger.
