At 17:03:16 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 170801 ***A*** (trigger=765783). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 290.481, -17.308 which is
RA(J2000) = 19h 21m 55s
Dec(J2000) = -17d 18' 27"
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 ~1171 counts/sec (15-350 keV), at ~0 sec after the trigger.
