At 12:03:23 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 220118 ***A*** (trigger=1093693). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 245.136, -15.846 which is
RA(J2000) = 16h 20m 33s
Dec(J2000) = -15d 50' 44"
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 ~7918 counts/sec (15-350 keV), at ~-1 sec after the trigger.
