It was rainbow shaped in the front that was being propelled forward causing a rippling effect.

I live near central Phoenix. At 2:10 am I was looking south and saw something in the sky moving from West to East. It looked like it was near South Mountain. It was at the altitude a plane would fly. It was like a red, orange, and silver energy field propelling something forward. The front had a rainbow shape and every few seconds it would propel something forward and make a little ripple effect. I didn't see a definitive aircraft only this strange energy field. That's the best way to describe it. It didn't fade out, it just kept going. I didn't see any kind of fire, just this sparkly like energy field propelling something forward. My view was obstructed by a building so I didn't see it for long. It was big. It had to have been caught on camera. I'm surprised the news didn't report it, but they're controlled by the government so I understand. This was like nothing I have ever seen, and I've seen a lot living in Phoenix. This was not a human aircraft. It was not fireworks or a bomb or a meteor. This had to be some type of alien craft. Thank you for listening. Please contact me if you would like to speak to me.
