Shining cylinder hovered then disappeared instantly

I was driving north on Byhalia Rd just before the train tracks and I saw a very bright shining object, possibly cylindrical, hovering at approximately 3,000 feet.
It was not shaped like a helicopter, nor was it making any noise. It was not a plane because it was not moving in a line- it appeared to be wobbling back and forth while hovering.
I decided to find a safe spot to pull over and get a better look, maybe take a picture. As I was about to turn into a parking lot, it completely disappeared, as if someone flicked a switch. I continued to look around to see if it had simply moved elsewhere very quickly, but there was absolutely nothing there-nothing but clear blue sky.
