Any idea what this might be??

I took this picture the other day, but didn't think much of it, until yesterday when I was going through my camera and saw the green thing in the top left corner, nothing like it is on any of the other photos that I took, and I have no idea what it is lol, so any ideas??

Light flare off the lens.

Ok thanks

It's a good picture. Maybe it's a UFO!

I had one similar to that and I thought ghost type thing....but as Dawn said, I was told it was just the light. Then you never know.................xxxxxxxxxxxxxxxx
