Vertical grey UFO caught over Laguna Woods, CA

On June 10, 2017, a weird metallic object is appeared floating across the sky over Laguna Woods, California, USA. What is it?

Witness statement:

On Friday, June 10, 2017 @ 5:15pm it was a cool evening not a cloud in the blue sky. I was sitting on my balcony in Laguna Woods talking to a friend facing East. While gazing at Saddleback mountain I noticed a shimmering metal object in the sky & thought it was a plane at first. As I kept my eye on it I realized that it was too vertical looking to be a plane so I grabbed my binoculars to see what it was. While looking through the binoculars I saw a pulsating red light coming from within the center column of the object, couldn't see the red light without the binoculars so I decided to grab my DSLR camera 16-270mm lens to take a few shots of it & look at it through my viewfinder. The object moved out of view before I could grab my tripod to get better shots. The consecutive shots shows that the object was changing in appearance & I believe rotating in circles while moving west in a straight line across the sky towards the ocean.
