At 09:27:32 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 171211 ***A*** (trigger=796469). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 98.108, -58.670 which is
RA(J2000) = 06h 32m 26s
Dec(J2000) = -58d 40' 10"
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 ~2441 counts/sec (15-350 keV), at ~0 sec after the trigger.
