At 01:13:16 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 170813 ***A*** (trigger=767563). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 201.054, -5.469 which is
RA(J2000) = 13h 24m 13s
Dec(J2000) = -05d 28' 07"
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 ~2115 counts/sec (15-350 keV), at ~-6 sec after the trigger.
