At 23:45:16 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 211017 ***A*** (trigger=1079966). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 244.979, -15.842 which is
RA(J2000) = 16h 19m 55s
Dec(J2000) = -15d 50' 31"
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 ~890 counts/sec (15-350 keV), at ~1 sec after the trigger.
