At 21:32:39 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 110709 ***A*** (trigger=456967). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 164.614, -23.484 which is
RA(J2000) = 10h 58m 27s
Dec(J2000) = -23d 29' 01"
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 ~4299 counts/sec (15-350 keV), at ~30 sec after the trigger.
