At 13:49:27 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 100906 ***A*** (trigger=433509). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 28.709, +55.614 which is
RA(J2000) = 01h 54m 50s
Dec(J2000) = +55d 36' 50"
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 ~11648 counts/sec (15-350 keV), at ~183 sec after the trigger.
