Observatory at Keystone College

The Thomas G. Cupillari ’60 Observatory, located a short drive from our La Plume campus in Fleetville, PA, promotes an understanding of the night sky along with a general knowledge of astronomy for the Keystone College community and the general public.

Whether you’re taking an astronomy course or just interested in the night sky, the observatory at Keystone College offers a unique, hands-on learning experience. Observing the night sky and finding objects using a telescope will help open the wonders of the universe. Whatever your ambitions in astronomy, we can help you get started.

Thomas G. Cupillari Observatory ’60 has been issued an Observatory Code I17 designation from the Minor Planet Center.

Observatory Public Viewing and Lecture Programs

Our programs offer an illustrated lecture, and if the sky is clear, observation of the night sky through the telescopes. Objects to be viewed include the moon, the planets, double stars, star clusters, nebulae, and galaxies, weather permitting The scheduled programs are provided as a community service and are free of charge. No registration required.

Fall Viewing Series at the Observatory

September 5 – November 16, 2018: The public lectures and viewing sessions will be conducted every Wednesday, with a repeat of the session on Friday evening. Lecture time: 7:30 p.m.

Groups Welcome

Due to limited seating, groups such as school classes, scouts, and community organizations must make an appointment for private lecture and observation on a night other than scheduled public viewing nights. Group nights are only scheduled on Monday nights.

2018 Events for Scranton, Pennsylvania

November

The two planets in the sky now visible to the naked eye are Saturn and Mars. Uranus and Neptune are also in the sky, but only visible in a telescope. The Moon will be 3 degrees left of Saturn on the 11th of the month. By the 18th the Moon is near equal distance between Saturn on the right and Mars on the left of the Gibbous Moon. By the next night, the 19th a Gibbous Moon stands above Mars by less than 5 degrees

December

To the start of this month is a telescopic treat. Mars will pass close by the outer planet Neptune on the night of the 7th this month, it will very close paring during the afternoon hours. By nightfall they will be visible at low magnification in a telescope. Mars, only 8.8 arc seconds in angular diameter now, and Neptune will be only 15 ARC SECONDS apart in our skies! Neptune will be the lower right of Mars a 8.0 magnitude a small 2.3 arc second angular disc. Don’t be confused by the 6th magnitude star above Mars.

The Geminid Meteor Shower show be a good early morning show on the night of the 13th and morning of the 14th. The Moon will set around midnight; so get rested early to stay awake in the early morning hours. But be sure look for the Moon and Mars on the evening of the 14th. The Moon will be less than 5 degrees below Mars.

Saturn is leaving our skies this month. It will be over the western horizon by the end of the year. Mars is still hanging on.

The planet Mercury will be seen in the morning sky in December, on the morning of the 7th it will be farthest from the Sun. This is the best time to view Mercury since it will be at its highest point above the horizon in the morning sky. Look for the planet low in the eastern sky just before sunrise. Jupiter will join Mercury in the sky later in the month. On the 21st they will be separated by less than one degree, a great way to find the elusive planet Mercury.
