Found this on my camera today

I was out cleaning the paddock and hanging out with my horses today (my happy place), and taking a few pictures. When I uploaded them to my computer I realized this one must have been shot as I was putting my camera away. There appears to be a swirl of green/yellow 'energy'circling me It was overcast so I don't think this could be a reflection and the camera was pointed at the ground anyway... could this be an aura?
