White light between 1000 and 5000 feet above moved from a westerly to easterly direction.

I began to see the object/light from about a mile away. It had the brightness of a 100-watt light bulb at 300 feet away. It passed overhead at a steady speed, in a straight line. No blinking, no sound. A single white light. I watched it until it went out of sight, maybe 2 miles east of my home. I was on the back deck tossing the ball to one of my dogs when the event occurred.
There were a few light wispy clouds overhead. Several planes went by while I sat for 30 minutes, and they all went out of sight at moments because they were above the few clouds.
