I work nights and I was on my deck at about 2 am. The sky was clear, stars were present and little to no clouds. I saw this phenomenon over Burlington Twp on 11/17/15 at 2:30 am.After a falling flash of green light ,there appeared 6 orbs travelling north between the DE River and Rt 130. I thought maybe birds at first but then quickly dismissed that notion when the orbs began to perform. They were in a straight line formation, then changed to a V. then they split to 3 and 3. the center 2 orbs flew in sync while the others flew alternating patterns of circles, figure eights and colliding semicircles around them. It was an awesome display!I am absolutely certain of what I witnessed. It took about 90 seconds for this all to happen before I lost view over the horizon. Then I began to think who else could have seen it. Anybody travelling on the Burlington Bristol Bridge or PA Turnpike Bridge in Florence would have had the highest vantage point. Then I checked your site and noticed that somebody saw something similar to what I saw in VA earlier, and even before that in the Carolinas.Maybe somebody else will report it further North.I have always believed but this was my first encounter.
