At 12:20:23 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 240119 ***A*** (trigger=1209635). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 256.363, -37.847 which is
RA(J2000) = 17h 05m 27s
Dec(J2000) = -37d 50' 47"
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 ~1062 counts/sec (15-350 keV), at ~3 sec after the trigger.
