At 23:13:10 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 260122 ***A*** (trigger=1443066). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 336.079, -59.167 which is
RA(J2000) = 22h 24m 19s
Dec(J2000) = -59d 10' 02"
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 ~0 counts/sec (15-350 keV), at ~ sec after the trigger.
