solid reddish orb, no lights 100 feet up and northbound at about 30mph.

saw sphere with solid red exterior hover silently and fast northbound. I was sitting in the dark with my wife outside and my eye caught the gleam of street lights reflecting off of the sphere. It was approximately 100 feet from the ground and had no lights of any kind.  I would say it was a balloon, but it was moving at about 30 miles an hour in a straight line north while the wind was blowing perpendicularly from the east.
