My wife, first spotted this object and my sons and i immediately came to look. it was the color of the moon, yet tinier. we live 15 mins from the phl airport and planes were flying around, so if it was probably on radar.. but hard to tell how high it was exactly. when i view this through my binoculars and slr camera it appeared to be a ring of light with small lights in the ring. i took some picture, but it's hard to see the small light, that looked like a ring of bright white leds. if you zoom on the picture, it very clear that it's a ring. it moved very slowly across the sky, no sound, no sudden movements, just a bright ring in the sky.
