At 04:37:10 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 240313 ***A*** (trigger=1219909). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 135.660, -39.428 which is
RA(J2000) = 09h 02m 38s
Dec(J2000) = -39d 25' 41"
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 ~976 counts/sec (15-350 keV), at ~7 sec after the trigger.
