At 13:57:11 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 081203 ***A*** trigger=336489). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 233.033, +63.498 which is
RA(J2000) = 15h 32m 08s
Dec(J2000) = +63d 29' 54"
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 ~4222 counts/sec (15-350 keV), at ~184 sec after the trigger.
