Would you like to spot the ISS? It's perfectly possible but you have to be in the right place at the right time. It orbits the Earth every 92 minutes travelling at 7.68 km per second. Its orbit is inclined to that of the Earths by 52.6 degrees. That means that it passes over most of the Earth's surface. Its orbit and the time that it passes over any given point is therefore predictable.

To the casual observer the ISS is only visible when it is illuminated by the Sun and the observer is standing on the dark side of the nightline. For all practical purposes this means just after sunset or just before dawn.

Although the computations are formidable, happily we have a website available that will do the calcs for you. Click on Heavens Above to insert your location and the site will show the predicted overflys of the ISS.

The table shows predicted passes by the ISS centred over Folkstone UK. Not all passes are listed, just the brightest and those with the best chance of observing.

Currently they are early evening, just after sunset. To be updated.
