Orange Orbs off the NC coast!

Sitting on the deck of our oceanfront rental home, 3 of us saw 2 orbs about 10 yards apart and about 40yrds above the oceans horizon.  These orbs were bright orange and circular in shape.  They appeared briefly for about 20 seconds and then quickly went out.  5 minutes later the orbs reappeared but this time seemed to be attached to one another.  The same orbs were seen the night before and seemed to be moving back and forth through the sky.  Sort of like a liquid motion.  Helicopters were noticed on the first night and although it was dark sounded like they were flying over the orbs location.  This didn't seem to be the case on the 2nd night.  There was no sound noticed with the orbs.
