Large spheres of light making formations across the sky with flickering lights coming and going.A friend and I were on her back patio and the "stars" looked extremely close. We began to notice some getting bigger and flickering. Most were spheres of light that would make different formations as if they were working together. Some appeared suddenly in the shape of a triangle and different colored flickering lights. Some appeared suddenly down low through the trees and vanished suddenly. There were different size circles of light. Some appeared blue, some appeared reddish orange and some were white and then faded in and out. One was moving in a circular motion repeatedly. Some would shoot down beams of light. It appeared to be several as if they were hovering and working together to create some type of formation.
