It was around 10:45 pm on a clear night in downingtown, pa. i had taken my dogs out back when i looked up to the east in the sky as residual fire works were being fired off, not a lot, just a couple here or there. above the exploding fireworks i had noticed 5 red/red-orange orbs clustered, either above or further off in the distance, and alternating two at a time oscillating in the sky. i thought they were dancing in the sky, two would go up and come back down and two others would go up and back down. i had called out my wife to take a look and she played it off as being fireworks. i told her fireworks don't go up and down multiple times and would have fizzled out after a few seconds. the orbs never dimmed in the time they were observed. after going back into the house to find a camera, for a few minutes, i came back out and the orbs were no longer visible.
