Flying low .saw orangish colored orbs floating across the sky in the western sky here in kansas heading north, no sound associated with the sitings, several were in groups of 4, arranged in a square formation, several were alone floating across the sky moving slowly to the north. Looked like approx.1000 ft. up in the sky. Wondering what these could be?
