At 21:10:37 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 230322 ***A*** (trigger=1161127). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 16.565, -47.729 which is
RA(J2000) = 01h 06m 16s
Dec(J2000) = -47d 43' 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 ~1292 counts/sec (15-350 keV), at ~-1 sec after the trigger.
