At 16:41:56 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 180623 ***A*** (trigger=844015). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 214.511, -60.294 which is
RA(J2000) = 14h 18m 03s
Dec(J2000) = -60d 17' 38"
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 ~6581 counts/sec (15-350 keV), at ~61 sec after the trigger.
