At 07:20:43 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 171205 ***A*** (trigger=794972). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 167.447, -12.604 which is
RA(J2000) = 11h 09m 47s
Dec(J2000) = -12d 36' 12"
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 ~863 counts/sec (15-350 keV), at ~7 sec after the trigger.
