A friend here at work took this photo. In the photo you'll find a series of dots in a very straight line, its near the pine tree in the foreground. I cropped and blew up the picture so you can see the detail in this photo.

I don't seriously think its a UFO, but I am interested in what you think would cause this.

Some info on the photo;
Exposure time - 16S
F-Stop - 4.0
14.6mm Focal length
One chip sensor
Kodak DX4900 camera.

My best guess is that is a meteor that got caught in the scan rate of the CCD. A digital camera scans each individual pixel of the CCD very quickly. On a long exposure, it does this several times. If a very fast event comes along, like a meteor, it doesn't record it as a streak, like a film camera does, but maybe a set of dots like we see in this photo?

All speculation on my part...I don't really know.

What do you think?

Sorta like your rocket video topic....

If it is not an an artifact of CCD processing AND orbital transit of a satellite or the ISS (there was enough light at that angle to reflect back on earth), it could be multiple pieces of something entering the atmosphere, but I did not notice any contrail - at least it was not clear in the blowup. Did the shooter notice the dots at the time of the photo shoot?
