At 10:23:11 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 140323 ***A*** (trigger=592916). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 356.888, -79.917 which is
RA(J2000) = 23h 47m 33s
Dec(J2000) = -79d 55' 00"
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 ~6671 counts/sec (15-350 keV), at ~89 sec after the trigger.
