At 23:52:59 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 190630 ***A*** (trigger=912239). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 293.908, -32.751 which is
RA(J2000) = 19h 35m 38s
Dec(J2000) = -32d 45' 03"
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 ~2116 counts/sec (15-350 keV), at ~0 sec after the trigger.
