Looks very fake to me, whats the source?
My theory is that the mind-altering properties of the plasma phenomenon causes people to legitimately think they are seeing that kind of classic chrome disk-shaped spacecraft, because of their pre-existing biases based on science fiction and popular culture - when in fact they are attributing this image to something that is merely a glowing ball of light - superficially similar to how a chrome object would appear in the sky. Thats the reason I think any photographs that definitively show the classic UFO form are forgeries - a legit photo would show the orb itself and not the human interpretation of it.
