Over the next week or so the International Space Station (ISS) will be rather bright - up to magnitude -3.6! Here is an image taken tonight (21st April 2011) at approx. 21:25 BST. The "star" to the bottom left is Saturn. (The other lines are phone cables).
The whole transit lasted about 5 minutes, this exposure is approx. 2 mins.
The ISS travelled west to east - that is right to left in the picture.
