COMMENTS: This matches a source in the ground catalog: Cyg X-1, delta=0.050 [deg].
COMMENTS: This is not a GRB.
COMMENTS: Since the IMAGE_SIGNIF is less than 7 sigma, this is a questionable detection.

At 23:38:32 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 160702 ***A*** (trigger=702630). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 299.645, +35.225 which is
RA(J2000) = 19h 58m 35s
Dec(J2000) = +35d 13' 29"
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 ~1843 counts/sec (15-350 keV), at ~1 sec after the trigger.
