At 11:11:51 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 180630 ***A*** (trigger=845443). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 48.810, -87.482 which is
RA(J2000) = 03h 15m 14s
Dec(J2000) = -87d 28' 54"
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 ~6502 counts/sec (15-350 keV), at ~4 sec after the trigger.
