Bright, white cylinder flying 1000 ft. above commercial plane.

I was driving eastbound on PA Turnpike ( I 70-76 ) at around 12:30 PM. The sky was clear blue and in the northeast sky I noticed an airplane with a very short contrail flying south. About 1000 ft. above the airplane on the same flight path I saw a bright, white, shiny cylinder shaped object flying above the airplane. The object was clearly not the same type of flying machine, much smaller but much brighter with a halo type effect surrounding it. Unfortunately, it was a very short sighting due to winding road through the mountains and since I was traveling at 75 mph on a busy interstate, I was not able to get a photo.
