At 04:01:35 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 240109 ***A*** (trigger=1207446). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 301.318, +16.578 which is
RA(J2000) = 20h 05m 16s
Dec(J2000) = +16d 34' 39"
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 ~3164 counts/sec (15-350 keV), at ~0 sec after the trigger.
