Starting tonight there are several excellent opportunitites to see the Chinese space station, Tiangong 1, fly over. This unmanned station appears like other satellites, as a star (sometimes as bright as magnitude 0) travelling across the sky in a straight line and with no blinking lights.

Accompanying it is the Shenzhou 8, an unmanned craft being used to practice docking. The Shenzhou 8 will appear as a fainter light in the same orbital path, but could appear before or after the station. We don’t know how long the docking practice will continue, so get out and see this pair while you can.

Here is a link to the Heavens-Above website with sighting predictions for the station. Good luck!

*****UPDATE*****
Shenzou 8 successfully returned to earth on November 17. You can still catch the Tiangong 1 space station as it flies overhead.
