The cylinder seemed transparent with swirling red,orange and yellow particles and a detached sphere behind it.

I was swimming in my swim spa when I noticed a dark shadow in the sky no light was being emmitted to the naked eye. I could see nothing except a slight shadow .When I put my infrared binoculars on it I recorded 2 minutes of what I described above. At about 1 min a dark matter entered the cylinder and all the colored particles dissapeared The object slowly faded and started to dissapear. It seemed the camera was malfunctioning, but it was not. The infared records in B&W, I see color through the the lens. I have other recordings . Mt Shasta is about 50 miles away. I can send the video
