At 07:26:17 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 170906 ***A*** (trigger=770981). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 128.704, +70.782 which is
RA(J2000) = 08h 34m 49s
Dec(J2000) = +70d 46' 54"
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 ~4211 counts/sec (15-350 keV), at ~6 sec after the trigger.
