At 12:06:28 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 230510 ***A*** (trigger=1167973). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 318.156, +34.443 which is
RA(J2000) = 21h 12m 37s
Dec(J2000) = +34d 26' 33"
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 ~5163 counts/sec (15-350 keV), at ~13 sec after the trigger.
