I was sitting in my back yard at 10:36 AM after throwing the ball for my dog. I was sitting facing West and looked up in the sky. There were no clouds, however there were 5 white circular objects flying in unison back and forth in the sky. I thought they were birds, but they would get brighter and were moving in a slow uniform pattern. I though this was interesting and I had my cell phone with me so I recorded it. After 6 minutes and 7 seconds the 5 objects disappeared. They faded into the sky and were not seen again during my time in the yard.
