The Cornell Astronomical Society & Fuertes Observatory

The Cornell Astronomical Society (CAS) has conducted public viewing nights at Cornell University's Fuertes Observatory for over 40 years. We open the observatory every Friday night during the academic year from 8 PM until midnight, regardless of weather. During the summer, winter, and other Cornell breaks, we generally try to be open from 8 PM to midnight if the weather is clear. To find out if the observatory is currently open, check our Twitter at right or join our listserv at the bottom of the page to receive weekly updates on open houses and other events! Visit our Hours & Directions page for directions to the observatory, parking information, and a schedule of upcoming events.

 

The Observatory's main telescope is the Irving Porter Church Refractor, a 12-inch Brashear/Warner & Swasey achromat built in 1922. Several other smaller, more modern telescopes are also used for observing. Visit the Open House page for a list of likely targets and other information about open house nights at Fuertes.

Lectures to the public are given by Cornell astronomy faculty and other researchers several times throughout the semester on Friday nights (prior to observing); visit the Lecture Series page for a list of upcoming lectures. 

 

The Cornell Astronomical Society is Cornell's astronomy club. All Cornell students, regardless of prior experience or area of study, are welcome to become members of the CAS. Visit About the Club for more information on the CAS, including meeting and membership information.

Fuertes Observatory Tours and Group Events

Organizations and informal groups may request an educational observing session at Fuertes Observatory conducted by CAS volunteers. These can be arranged on non-Fridays and any night when the observatory is not reserved for introductory astronomy classes. Private sessions are completely free! Scheduling of events is subject to the availability of CAS officers and to the full discretion of the Cornell Department of Astronomy. Send us an email to arrange an event.
