At 02:40:46 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 240305 ***A*** (trigger=1218690). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 186.792, -61.931 which is
RA(J2000) = 12h 27m 10s
Dec(J2000) = -61d 55' 52"
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 ~820 counts/sec (15-350 keV), at ~7 sec after the trigger.
