It was a very slow moving satellite, I saw it appear when I was taking the images, it was on several frames and each frame was 2 minutes long.

There are two satellite tracks in the image, but I have not been able to identify either track.

I give up - can't find any data relating to anything passing through that section of sky at that time. Must be top secret.
