White Disk Passes Over Live Volcano On Cam, Aug 18, 2019, Video, UFO Sighting News.

I was looking over a live volcano cam when I found an unknown object flying through the plume of smoke over the volcano. The object has no wings, tail or contrail. When I focus the object using a photo program, it appears to be a white disk with a dark hump at its lower center. There are no identifying marks on the craft. Also the second cam in the upper left corner caught nothing at all. It was invisible to that cam! That sound like the cloaking technology of aliens to me. So I'm calling this a real UFO.
