At 05:17:50 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 240313 ***A*** (trigger=1219916). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 255.207, -38.212 which is
RA(J2000) = 17h 00m 50s
Dec(J2000) = -38d 12' 42"
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 ~804 counts/sec (15-350 keV), at ~6 sec after the trigger.
