At 15:41:14 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 180705 ***A*** (trigger=846299). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 212.594, -11.630 which is
RA(J2000) = 14h 10m 23s
Dec(J2000) = -11d 37' 48"
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 ~6491 counts/sec (15-350 keV), at ~4 sec after the trigger.
