At 20:06:10 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 221202 ***A*** (trigger=1142997). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 77.095, -59.806 which is
RA(J2000) = 05h 08m 23s
Dec(J2000) = -59d 48' 21"
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 ~1046 counts/sec (15-350 keV), at ~1 sec after the trigger.
