At 06:28:24 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 171029 ***A*** (trigger=783893). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 335.758, +67.859 which is
RA(J2000) = 22h 23m 02s
Dec(J2000) = +67d 51' 34"
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 ~3296 counts/sec (15-350 keV), at ~0 sec after the trigger.
