At 11:25:19 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 240208 ***A*** (trigger=1213829). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 245.167, -15.775 which is
RA(J2000) = 16h 20m 40s
Dec(J2000) = -15d 46' 28"
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 ~820 counts/sec (15-350 keV), at ~4 sec after the trigger.
