At 18:16:28 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 220711 ***A*** (trigger=1115766). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 261.993, +24.669 which is
RA(J2000) = 17h 27m 58s
Dec(J2000) = +24d 40' 10"
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 ~2146 counts/sec (15-350 keV), at ~0 sec after the trigger.
