At 13:25:33 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 180514 ***A*** (trigger=832368). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 197.401, +36.969 which is
RA(J2000) = 13h 09m 36s
Dec(J2000) = +36d 58' 10"
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 ~1339 counts/sec (15-350 keV), at ~5 sec after the trigger.
