At 07:08:05 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 201118 ***A*** (trigger=1007266). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 84.721, +26.327 which is
RA(J2000) = 05h 38m 53s
Dec(J2000) = +26d 19' 36"
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 ~1776 counts/sec (15-350 keV), at ~-6 sec after the trigger.
