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 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.

Minor Planet Project

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

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 Schedule: September 6 – November 17, 2017

Time: Lectures begin at 7:30 p.m.

The fall series of public lectures and viewing sessions will be conducted every Wednesday, with a repeat of the session on Friday evening.

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.

2017 Events for Scranton, Pennsylvania

May

Warmer month of May 7th is a good time to get out and see the near full Moon next to the bright planet Jupiter in the western sky during late evening twilight. Side by side and separated by 2 degrees, that’s less than half the separation of the two stars in Big Dipper asterism that point the way to the North star Polaris. Jupiter and the Moon will meet again in the sky next few months.

Venus and Mercury are now visible in the morning sky before sunrise. Mercury is climbing higher each day, reach only a maximum height of 10 degrees above the horizon. Use the planet Venus to draw an imaginary line to the point of sunrise to spot Mercury low on a clear unobstructed horizon. Venus (-4.4 mag.) and Mercury (0.0 mag.) are closest on the 19th May, by 19 degrees. However the planet Mercury is only 10 degrees above the horizon.  After which they begin to separate more each with Mercury rising higher above the horizon each day.

On the 23rd of May the thin crescent Moon is a good view of Venus and the Moon, Venus is higher up to the right of the Moon. From a clear unobstructed horizon the plane Mercury 9 degrees to the lower left of the Moon. Not an easy to see but worth a try.

Another challenging is viewing a 1-day-old moon, very thin crescent, on the evening of 26th of May. The moon will only be 10 degrees above the horizon at sunset. In the sky also is magnitude 1.0 planet Mars, some 6 degrees to the upper right of the Moon.  Seeing only the thin crescent Moon would be a rewarding view, seeing Mars would be an extremely difficult in early twilight.

By now you should have made plans to travel to see the Total Solar Eclipse that will be visible in the United States. The event WILL ONLY be a Partial eclipse from Northeastern Pennsylvania.

June

A good paring of Jupiter and the Moon can be seen on the evening of June 3 in the southern sky. The gibbous moon is less than 2 degrees above the -2.2 magnitude King of the planets. Both will fit into the field of view of binoculars.

A few days later, on the evening of June 9th, the Full Moon is 2.5 degrees to the upper left of 0.0 magnitude planet Saturn.

In the southwest sky on the evening of June 30th finds the First Quarter Moon less than 5 degrees right of the -2.2 magnitude planet Jupiter. Look for the Moon the next evening (July 1st), 8 degrees to the upper left of Jupiter.

July

Low on the southern horizon on July 6th the near Full moon be above the ringed planet Saturn. They will be separated by less than 3 degrees. Saturn and its family of moons will be a good sight in telescope.

AT NO TIME WILL THE MOON FULLY COVER THE SUN IN THE SKIES OF NORTHEASTERN PENNSYLVANIA

NEVER LOOK AT THE SUN WITH A TELESCOPE OR YOUR EYE ALONE. ONLY AN APPROVED SOLAR FILTER PLACE IN FRONT OF THE TELESCOPE OBJECTIVE LENS OR MIRROR, BEFORE LIGHT ENTERS THE TELESCOPE, SHOULD BE USED WITH A TELESCOPE.

AT NO TIME WILL THE MOON FULLY COVER THE SUN IN THE SKIES OF NORTHEASTERN PENNSYLVANIA IN  AUGUST 2017.

August

Close to the meridian in the southwest sky the gibbous Moon is place less than 3 degrees to the upper right of the planet Saturn on the evening of August 2nd. The next evening finds the Moon to 8 degrees to the left of Saturn..

A grand sight of the -4.4 magnitude planet Venus situated some 5 degrees directly above the thin crescent Moon in the early morning hour before sunrise on August 19th.

AT NO TIME WILL THE MOON FULLY COVER THE SUN IN THE SKIES OF NORTHEASTERN PENNSYLVANIA

Partial Eclipse times as seen from Scranton Pennsylvania

2017 Aug 21 2:18 pm Partial Solar Eclipse, First Contact, Alt=60°

2017 Aug 21 2:40 pm Partial Solar Eclipse, Mid-eclipse, Alt=54°

2017 Aug 21 3:57 pm Partial Solar Eclipse, Last Contact, Alt=42°

The crescent Moon in the evening sky at sunset on August 25th will be placed some 5 degrees to the upper left of the planet Jupiter.

September

The crescent Moon and brilliant planet Venus in the east on morning of Sept 17th will be key to star hopping to locate two other planets.  With the Moon 6 degrees to the upper right of Venus, draw an imaginary line from the Moon through Venus to the horizon where you may see the planets Mars and Mercury low near the horizon. Mercury is the brighter and closer to the horizon. Dimmer Mars is just a 1/2 degrees (size of the full Moon) to the upper right of Mercury hugged in a binocular view. Will be difficult due to fading twilight and requires a good clear horizon.

The following morning, Sept 18th, the crescent Moon is now place between Venus and the planets Mercy and Mars still hugged together. If you see another object close to Venus then you have spotted the bright star Regulus.

Jupiter is setting early each evening after sunset. Sept 22nd may be the last opportunity to see the crescent Moon and Jupiter together in the evening sky. The Moon is 7 degrees to the upper left of Jupiter, a clear horizon is need to find the planet.

Starting the last week in September keep a watch on Mars and Venus in the morning sky, as they will perform a close dance in the sky.

Once again you have the chance to see a near First Quarter Moon only 3 degrees above the ringed planet Saturn in SSW horizon on Sept 26th.

October

A conjunction of two planets will take place in the early morning sky is the first week of the month. Mars is rising up in the sky from the horizon, while brilliant Venus is descending quickly to the horizon each passing day. The two planets will pass very close to each, from our viewpoint from the Earth. Physically the two planets are millions of miles apart from each other. Venus will be just 15 arc minutes from the planet dimmer Mars on the morning of Oct 5th.

Watch each morning as Venus sets and Mars rises in the sky, then on the morning of Oct. 17th the thin crescent Moon will be less than 2 degrees right of the planet Mars and 7 degrees above Venus.

During the early evening of Oct 23rd the fat crescent Moon will be to the within 8 degrees of the ringed planet Saturn. On the following evening, Oct 24th, the Moon will be 3 degrees closer to Saturn and to the upper left.

November

The two brightest planets will pass each other in the morning sky, however the rising sun and the horizon view will make seeing these two close to each other, within 15 arc minutes on Nov 13th, a difficult challenge. Venus outshines Jupiter on it right. the two planets are only 13 degrees to the upper right of the Sun. Venus may be seen in binoculars, depending on the quality of the sky, Jupiter would be difficult

The crescent Moon some 6 degrees to the lower left of -1.8 magnitude Mars on Nov 15th should be visible, if a clear horizon and cloudless skies prevail.

December

In the morning sky the planet Mercury and Venus are too close to the Sun to be seen.  Higher up in the morning sky are the planet Mars and Jupiter. They are join by the fat crescent Moon on the morning of Dec 13th, the Moon less than 5 degrees above Mars, and the Red planet 12 degrees to the upper right of Jupiter. the following morning, Dec14th the crescent Moon is 4 degrees above bright planet Jupiter.  This is also the peak days of the Gemini meteor shower.

Will the sky be clear?

The clear sky chart numerical weather forecast is specifically designed for astronomers and will predict if the Thomas G. Cupillari ’60 Observatory will have good weather for astronomical observing. At a glance, the sky chart shows when it will be cloudy or clear for the next two days.
