At 02:19:00 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 241213 ***A*** (trigger=1274039). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 116.148, +35.280 which is
RA(J2000) = 07h 44m 35s
Dec(J2000) = +35d 16' 49"
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 ~9527 counts/sec (15-350 keV), at ~0 sec after the trigger.
