I think it's a very big rock... I did, at first, think it might have been a speck or something on the lens, but it has lighting and shadow. I even tried to see it through binoculars... still didn't see it with my eyes.
I took a shot of my ceiling fan spinning... the camera, in vga (lowest) mode, caught the blades as if they were standing still... no blur. The wonders of technology ;-)
