At 03:36:28 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 240516 ***A*** (trigger=1228797). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 212.770, -63.505 which is
RA(J2000) = 14h 11m 05s
Dec(J2000) = -63d 30' 17"
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 ~1829 counts/sec (15-350 keV), at ~184 sec after the trigger.
