At 08:37:41 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 071018 ***A*** trigger=294645). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 164.676, +53.830 which is
RA(J2000) = 10h 58m 42s
Dec(J2000) = +53d 49' 49"
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 ~1476 counts/sec (15-350 keV), at ~7 sec after the trigger.
