The Cornell Astronomical Society & Fuertes Observatory
Founded in 1972, the Cornell Astronomical Society (CAS) is a Cornell University undergraduate student organization, and has run public observing nights at the Fuertes Observatory for nearly 50 years. The club is open to Cornell undergraduate and graduate students, but faculty and staff members also occasionally volunteer at Fuertes Open House Nights and other Astronomy Department outreach events. Club members are given opportunities to learn how to use the historic 12" Irving Porter Church Refractor (finished in 1922) as well as many other telescopes at Fuertes.
We open the observatory every Friday night during the academic year from 8:00 PM until midnight, regardless of weather. During the summer, winter, and other Cornell breaks, we generally try to be open from 8pm to midnight if the weather is clear. To find out if the observatory is currently open, call (607)-255-3557 for a prerecorded message. You can visit our Hours & Directions page for directions to the observatory, parking information, and a schedule of upcoming events.
