At 16:13:08 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 220305 ***A*** (trigger=1095215). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 107.584, -37.708 which is
RA(J2000) = 07h 10m 20s
Dec(J2000) = -37d 42' 29"
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 ~1449 counts/sec (15-350 keV), at ~0 sec after the trigger.
