At 18:51:40 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 210807 ***A*** (trigger=1064380). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 245.114, -15.937 which is
RA(J2000) = 16h 20m 27s
Dec(J2000) = -15d 56' 10"
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 ~1015 counts/sec (15-350 keV), at ~0 sec after the trigger.
