At 05:55:51 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 181010 ***A*** (trigger=866434). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 52.557, -23.035 which is
RA(J2000) = 03h 30m 14s
Dec(J2000) = -23d 02' 06"
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 ~2480 counts/sec (15-350 keV), at ~8 sec after the trigger.
