At 15:20:29 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 171102 ***A*** (trigger=785510). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 288.103, +22.438 which is
RA(J2000) = 19h 12m 25s
Dec(J2000) = +22d 26' 16"
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 ~1617 counts/sec (15-350 keV), at ~4 sec after the trigger.
