At 17:46:23 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 240216 ***A*** (trigger=1215690). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 300.851, +35.088 which is
RA(J2000) = 20h 03m 24s
Dec(J2000) = +35d 05' 18"
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 ~1070 counts/sec (15-350 keV), at ~7 sec after the trigger.
