Date of sighting: July 23, 2013
Location of sighting: La Jolla, California, USA
I was having lunch with my wife at the Torrey Pines Glider port and I snapped a few photos of the parasailers with my Fuji X100 camera. A few days later when I downloaded the images onto my computer I noticed a dark smudge in 1 frame of my images. The image was made with a Fuji X100 camera which has a fixed lens and is sealed to outside elements which ruled out dust or dirty sensor. I have no idea what it is but appears to be moving at a high rate of speed and appears to be below the clouds.
