Night sky objects

The International Space Station or ISS is by far the largest single artificial body in orbit around the earth.  With the exception of our sun it is also - when caught by the right light - the single brightest object in our sky.  Listed below are the best long-duration opportunities to locate and watch it and related vehicles as they pass over (clear skies permitting, of course), although only the ISS is likely to be visible to the naked eye.

Very occasionally, other vehicles or objects will be listed as visible, although they will be very much dimmer than the ISS.

Sightings derived from TLE data obtained from Celestrak using the PyEphem package.
