Helicopter and red/orange orb sighting.I observed a helicopter being trailed by a red/orange orb that from my vantage point appeared smaller than the copter. It trailed 20 meters behind it at the beginning of my sighting then overtook it in one fluid motion.It paced the copter 20 meters ahead after. I lost site of both when a home blocked my vision.What convinced me was the fluidity by which it went from behind then in front of the chopper... smooth as silk.Heicopter made sound and cabin was lit. Orb was not audible.
