At 14:48:34 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 230216 ***A*** (trigger=1154815). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 113.966, -8.015 which is
RA(J2000) = 07h 35m 52s
Dec(J2000) = -08d 00' 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 ~992 counts/sec (15-350 keV), at ~0 sec after the trigger.
