At 05:21:49 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 210315 ***A*** (trigger=1036990). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 299.740, +35.403 which is
RA(J2000) = 19h 58m 58s
Dec(J2000) = +35d 24' 09"
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 ~1312 counts/sec (15-350 keV), at ~0 sec after the trigger.
