At 19:08:50 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 170604 ***A*** (trigger=755867). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 342.645, -15.414 which is
RA(J2000) = 22h 50m 35s
Dec(J2000) = -15d 24' 50"
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 ~2468 counts/sec (15-350 keV), at ~0 sec after the trigger.
