At 08:23:06 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 171027 ***A*** (trigger=783479). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 61.680, -2.606 which is
RA(J2000) = 04h 06m 43s
Dec(J2000) = -02d 36' 21"
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.
