To see a satellite from the ground, you need them to fly over at just the right time - either dawn or dusk. In daytime, the sky is too bright to see them. At night, the satellites are in the shadow of the Earth an so cannot be seen.

The next six weeks are the perfect time to see the space station flying over head.

The amazing image to the left were taken by Dirk Ewers of Hofgeismar, Germany, using just a 5 inch refracting telescope!

If you want to see the space station fly overhead, all you need to know is when and where to look - which the very easy-to-use satellite tracker will tell you.

The International Space Station can get extremely bright. Don't forget - If you see something passing over head with a flashing light, then it is a aircraft! If it has a constant brightness, it is a satellite. Also, satellites disappear suddenly as they enter the shadow of the Earth.
