At 14:55:27 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 200513 ***A*** (trigger=972030). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 245.163, -15.746 which is
RA(J2000) = 16h 20m 39s
Dec(J2000) = -15d 44' 44"
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 ~1273 counts/sec (15-350 keV), at ~0 sec after the trigger.
