    I have tried to identify this satellite.
    According to my simulation with Guide 8 and using TLE's from August 4
    I found that Envisat was at 20h 36m 15s in an area in Cygnus (Swan) where at
    20h 40m 18s the rocket of Kosmos 1674 (1985-069B) moved about in the
    direction you specified.
    
    Looking at your location's coördinates I see that it is not so far from me,
    I guess about 50 km (30 miles).
