At 01:53:06 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 220702 ***A*** (trigger=1114148). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 264.572, -26.964 which is
RA(J2000) = 17h 38m 17s
Dec(J2000) = -26d 57' 49"
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.
