Daylight sighting of Oval shaped Object.

I was at my River lot on the West Branch of the Susquehanna, and I happened to look to the West, when I saw the object. I would estimate its altitude at 2500 to 3000 feet AGL. The object moved in a straight line, and I watched until it entered clouds. There was no discernable fuselage, wings, or empennage. The object seemed to have a luminescence of it's own. I was able to catch video with my cellphone. There was boat traffic at the time, and other background noise, but no sound from the object. I am a Licensed Private Pilot, and a Military Aviation Buff, and are familiar with many different aircraft, both civilian, and Military, and this object didn't correspond to anything that I am familiar with.
