At 15:36:18 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 180613 ***A*** (trigger=840853). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 211.562, -43.076 which is
RA(J2000) = 14h 06m 15s
Dec(J2000) = -43d 04' 31"
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 ~1375 counts/sec (15-350 keV), at ~0 sec after the trigger.
