At 05:35:44 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 241209 ***A*** (trigger=1273071). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 155.376, +6.316 which is
RA(J2000) = 10h 21m 30s
Dec(J2000) = +06d 18' 58"
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 ~2562 counts/sec (15-350 keV), at ~0 sec after the trigger.
