At 16:34:47 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 240117 ***A*** (trigger=1209403). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 83.460, +22.287 which is
RA(J2000) = 05h 33m 50s
Dec(J2000) = +22d 17' 14"
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 ~890 counts/sec (15-350 keV), at ~5 sec after the trigger.
