I was driving home down 7 mile rd in pamplico, south carolina around 9:30 pm,when i observed two lights in the sky that appeared out of place. it was clear out, and several stars were visible but, these two seemed different. while watching them they moved and swapped position with one another. their movement was arced and rather quick, faster than a jet or airplane would have appeared at that elevation. suddenly, one them ascended, or possibly shrunk, until it was completely out of sight. the other remained in position for about another ten seconds and then simply disappeared from sight suddenly. these objects were comparable in size, and brightness, to the night's stars, but we're visibly lower in the sky. they appeared to be some distance apart but, were able to switch position in the sky with each other very quickly. i observed them for around 10 seconds before they changed position, watched them hover for around two minutes, then they were gone. at some points by view was blocked by trees. however, for most of the time they were in my view.
