I was looking at an airplane travelling overhead with my daughter from our backyard this afternoon. She pointed out another "plane" but I noticed it wasn't moving much, like it was holding its position in the sky pretty well. I could not tell the altitude, but it was pretty high up and no sound was audible. It was a windy day, so i ruled out a balloon or a bird. Then, after getting my wife to verify what I saw, I snapped several photos of the object. It slowly started to drift to the south/south west for a couple of miles (took about 30 seconds) then held that position again for a couple of minutes. Then, it rapidly flew back towards the original position in an arced flight pattern and held for a few seconds before vanishing. My wife and I saw the disappearance. Then in a matter of seconds it reappeard close to the second position it was hovering for a short time before vanishing after less than a minute.
