At 22:01:47 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 180512 ***A*** (trigger=832119). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 201.953, +21.406 which is
RA(J2000) = 13h 27m 49s
Dec(J2000) = +21d 24' 23"
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 ~1070 counts/sec (15-350 keV), at ~4 sec after the trigger.
