Bright Star object , that began moving upwards and towards the north, faded out of sight in clear night sky

As I went outside to walk to my mail box I looked up and noticed the planet Jupiter high over head and to the south. I also notice another very bright object slightly to the north of the Planet Jupiter same apparent magnitude and wondered which planet could it be?  As I watched the other bright object I noticed that it was now moving to the north. I thought maybe it might be the international space station and seemed to be moving at the same apparent speed as when I had seem International Space station fly over the Port Huron area earlier this year.
As I watched the Bright moving object I noticed that it appeared to be fading as it moved as though it was moving upwards as well as moving northward.  It was at this time I ran back inside to get my 10x50 binoculars to get a better look at this object.
My binoculars were just inside the doorway sitting on my lap table and by thee time I got back outside the bright object was nowhere insight.
I thought maybe that maybe clouds might have been obscuring my view and causing this apparent movement, but I noticed I was still seeing the backgrounds stars and the once bright object was now completely out of sight.
As a FAA licensed Commercial Pilot and backyard Astronomer I know the night skies and most man-made objects flying in them.
This was a most unusual brief sighting of something unknown to me!
