At 11:05:46 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 240123 ***A*** (trigger=1210276). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 199.319, +60.632 which is
RA(J2000) = 13h 17m 16s
Dec(J2000) = +60d 37' 53"
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 ~1175 counts/sec (15-350 keV), at ~5 sec after the trigger.
