At 6pm in Redding, CA I saw a very large ( 500 feet+ diameter ) roundish cloud-white globe UFO traveling south in the thundercloads, for a moment it was completely visible as it remained motionless then kept traveling south in the thunderclouds. I noticed two small round globes at the big globes base. I was talking on my cell phone to my friend when I saw the UFO, and appearently I talked really excited and was shocked.
