At 17:40:33 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 220319 ***A*** (trigger=1098132). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 218.207, +61.289 which is
RA(J2000) = 14h 32m 50s
Dec(J2000) = +61d 17' 20"
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 ~1867 counts/sec (15-350 keV), at ~0 sec after the trigger.
