Last night I saw an orange star in the sky above downtown slc. Then I noticed it had lightning type spider legs come out,and almost shoot a ray of light at something. After it seemed like beams of light were falling from the object. It would move short but swiftly. It looked like it was defending itself against an attack of some sort, the lightning rays shooting out of it seemed defensive, as a small blink of light would approach it, then the orange lightning would shoot in it's direction, followed by a beam of light that seemed to travel a good distance through clouds. I have never seen anything like it and I just sat there for about an hour watching this star wars type battle in the sky.
