At 11:26:43 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 181002 ***A*** (trigger=865036). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 64.736, +15.233 which is
RA(J2000) = 04h 18m 57s
Dec(J2000) = +15d 13' 60"
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 ~941 counts/sec (15-350 keV), at ~0 sec after the trigger.
