Celestial and Horizon Coordinates Explorer
This applet is created by the astronomy education team at the University of Nebraska. All the applets in this course are created by them, and available at their site.
The applet summarises the material in this session, and allows you to see how the celestial sphere and horizon diagram are related anywhere on Earth. You can also add stars, and look at their diurnal paths. The applet will be very useful to you in all the future lab sessions.
