At 08:42:38 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 210307 ***A*** (trigger=1036139). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 119.190, -66.963 which is
RA(J2000) = 07h 56m 46s
Dec(J2000) = -66d 57' 45"
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 ~1268 counts/sec (15-350 keV), at ~3 sec after the trigger.
