Please forgive the murkiness of this one. If we can get a brighter version, we'll post it. It was captured at Warmington House in North Cornwall, UK. It is very short, only a few seconds long. Keep your eye on the bottom left corner of the screen. You will see a mist that appears to be propelled across the dark. It doesn't appear fake.

As we get more of these, we will be sure to post them on this site.
