At 04:57:29 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 210730 ***A*** (trigger=1062150). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 149.592, +69.705 which is
RA(J2000) = 09h 58m 22s
Dec(J2000) = +69d 42' 19"
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 ~5515 counts/sec (15-350 keV), at ~0 sec after the trigger.
