At 20:52:56 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 211207 ***A*** (trigger=1088376). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 149.625, -24.352 which is
RA(J2000) = 09h 58m 30s
Dec(J2000) = -24d 21' 05"
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 ~1960 counts/sec (15-350 keV), at ~0 sec after the trigger.
