At 00:58:00 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 180329 ***A*** (trigger=819301). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 329.298, -15.071 which is
RA(J2000) = 21h 57m 11s
Dec(J2000) = -15d 04' 14"
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 ~1431 counts/sec (15-350 keV), at ~5 sec after the trigger.
