At 11:10:45 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 170109 ***A*** (trigger=731183). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 259.882, -24.994 which is
RA(J2000) = 17h 19m 32s
Dec(J2000) = -24d 59' 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 ~1203 counts/sec (15-350 keV), at ~-1 sec after the trigger.
