At 08:43:31 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 181110 ***A*** (trigger=871316). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 302.342, -36.903 which is
RA(J2000) = 20h 09m 22s
Dec(J2000) = -36d 54' 08"
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 ~3870 counts/sec (15-350 keV), at ~10 sec after the trigger.
