At 10:56:25 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 190322 ***A*** (trigger=894268). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 314.656, +41.785 which is
RA(J2000) = 20h 58m 37s
Dec(J2000) = +41d 47' 05"
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 ~0 counts/sec (15-350 keV), at ~ sec after the trigger.
