International Space Station

Here it is photographed above a cloudy sky in West London at 17:12 UTC  21/12/2012
It's path was captured as it transited West to East. The Moon is seen to the top right and
the track crosses the constellation of Purseus before appearing to pass the planet Jupiter.
The stella objects are trails rather than points of light due to the two minute exposure.

The ISS orbits the earth 15.5 times a day at an average speed of 27,700 kph.
at an average altitude of 350 km. The track is over a different place each orbit.
