Public Viewing Schedule


The Cline Observatory is open to the public for viewing every clear Friday night throughout the year.

The viewings begin ½ hour after sunset during March-October, and at 7:00 during November-February. (Determine sunset time for a particular date.)  Sessions usually last about two hours, but may run longer or shorter depending on interest and sky conditions.

For updates regarding how weather or other issues will affect this week's session, check our Twitter Updates Page @gtccastro.

For other questions about the observatory and its programs, contact Tom English at or GTCC extension 50023.

There is no charge for public night viewing and the observatory is open to anyone wishing to attend. No reservations are necessary, and there are no limits on the number of attendees. (We do ask that you let us know well ahead of time if you plan to bring a large group.)
