At 18:39:48 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 170405 ***A*** (trigger=745797). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 219.810, -25.244 which is
RA(J2000) = 14h 39m 14s
Dec(J2000) = -25d 14' 36"
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 ~5012 counts/sec (15-350 keV), at ~4 sec after the trigger.
