At 12:39:09 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 170205 ***A*** (trigger=736843). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 262.151, -0.053 which is
RA(J2000) = 17h 28m 36s
Dec(J2000) = -00d 03' 08"
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 ~19065 counts/sec (15-350 keV), at ~0 sec after the trigger.
