COMMENTS: This is a rate trigger.
COMMENTS: A point_source was found.
COMMENTS: This does not match any source in the on-board catalog.
COMMENTS: This does not match any source in the ground catalog.
COMMENTS: This is a GRB.
COMMENTS: Since the IMAGE_SIGNIF is less than 7 sigma, this is a questionable detection.

At 09:02:38 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 211203 ***A*** (trigger=1086826). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 170.174, +16.256 which is
RA(J2000) = 11h 20m 42s
Dec(J2000) = +16d 15' 21"
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 ~3000 counts/sec (15-350 keV), at ~7 sec after the trigger.
