At 07:40:19 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 220302 ***A*** (trigger=1094950). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 301.432, +49.389 which is
RA(J2000) = 20h 05m 44s
Dec(J2000) = +49d 23' 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 ~1156 counts/sec (15-350 keV), at ~2 sec after the trigger.
