At 07:57:27 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 240117 ***A*** (trigger=1209371). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 245.761, -15.964 which is
RA(J2000) = 16h 23m 03s
Dec(J2000) = -15d 57' 51"
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 ~1066 counts/sec (15-350 keV), at ~6 sec after the trigger.
