Saucer shaped aircraft caught in picture of storm

While trying to capture a beautiful storm rolling in, I saw the flying object decent from two major storm cells. It hovered for about 7-10 seconds and suddenly shot off at very high speed back into the clouds. I looked around my balcony which is around fifteen feet above the ground for any other witnesses but there were none. I later found that I had captured a picture of the flying object. If this machine is man made, we have some really amazing aircraft in this country.
