At 21:29:04 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 231210 ***A*** (trigger=1201696). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 95.772, -48.359 which is
RA(J2000) = 06h 23m 05s
Dec(J2000) = -48d 21' 32"
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 ~7948 counts/sec (15-350 keV), at ~-22 sec after the trigger.
