Pulsing green orb shaped UFO arcing across the sky Simpsonville SC.

A large pulsing green oval UFO Sighting traveled across the sky in an arcing trajectory in a horizontal direction. The UFO was lower than the typical altitude of a plane, but higher than the tree line. The UFO moved at relatively fast pace towards the north. I slowed my vehicle to try and track the UFO, but it had already accelerated out of sight. nuforc Simpsonville SC 2/21/17 UFO Sighting report
