At 01:41:00 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 200122 ***A*** (trigger=950330). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 209.981, +27.566 which is
RA(J2000) = 13h 59m 55s
Dec(J2000) = +27d 33' 56"
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 ~10984 counts/sec (15-350 keV), at ~10 sec after the trigger.
