At 17:31:14 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 090809 ***A*** trigger=359530). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 328.645, -0.083 which is
RA(J2000) = 21h 54m 35s
Dec(J2000) = -00d 04' 59"
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 ~1738 counts/sec (15-350 keV), at ~184 sec after the trigger.
