Interactive Star Chart

This chart of the sky above Arlington, VA will always be available here, and will be linked from our science page as well.

The map is initially displayed at the current time. Choose other times using the column at the right, and change the overlayed information using the buttons at the bottom. Star charts generated by Stellarium.

The overlays use transparent PNGs, which do not work on older versions of Internet Explorer.  Please direct comments or questions to Lee Phillips.
