Shining changing shape as it moved

While driving I noticed something shining and moving in the sky to my left I cousins figure out what it was and pulled over when process of elimination in my head concluded that I had no idea what it could be. I started taking pics and video as it moved around sometimes looking like a blimp and others like a disk or a giant parachute but It was large and to me unexplainable. I drove off and watched it as best I could as it disappeared. It was above the Otis Air Force base as I was driving past the base at that point so I thought maybe it was something to do with the military base. I didn’t know we could report things like this until recently. I showed my husband that day and he said it could be weather balloon (and maybe it is) So I forgot about having the photos assuming he was right Until I learned you can use this website.
