Super-charged Orb Ghost Picture

Debbie sent us this ghost picture of a super-charged orb moving across the field:

"I took this at yet another fire on our home place. About the same spot where Randy's bright orb was in your may issue. If you all have a clue what this is I'd like to know. If not it's ok... No, I didn't move the camera. And there is no other light source coming from the ground."
