There was much ballyhoo surrounding the penumbral lunar eclipse that would take place the night of July 4 – 5, 2020. We joined in just to explain a little about what was going on and what might be expected. Penumbral lunar eclipses take place when the Moon passes through the thin outer shadow Earth casts out into space; they are often very subtle, slight, and in this case, nearly undetectable. Just witness the photo above that shows the Full Buck Moon about one-half hour before maximum eclipse and the Moon at maximum. Casual observers saw no change across the entire event and it’s hard for us to see the difference even in photos that can be made to emphasize features! So we apologize if you waited up to see what we called the  “subtle” eclipse but, if you did, you saw a beautiful Full Moon!

Then there was the much-less-promoted Sunday night, July 5, conjunction of Earth’s Moon, with planets Jupiter and Saturn… a lovely sight! We went out to photograph it an hour after moonrise and spied a brilliant orange Moon lighting up the scattered clouds with Jupiter shining through and Saturn making a somewhat dimmer appearance. A conjunction is when two or more celestial objects appear close together in our skies — emphasis on appear since Moon, Jupiter, and Saturn are separated by hundreds of millions of miles. We were surprised to see, in the photo below, that even Jupiter’s four Galilean Moons can be seen. The stars and planets appear oblong or as short streaks due to Earth’s rotation and the length of the camera exposure.

A penumbral lunar eclipse occurs when the Moon passes through the thin outer shadow — penumbra — Earth casts out into space.

We’re fortunate that the night of July 4 is expected to be clear, and not just for the traditional booms and flashes of celebratory fireworks. Our Moon is getting in on the act, albeit with a much more subtle display in the form of a penumbral eclipse. The eclipse will take place from 11:07 PM to 1:52 AM EDT with maximum eclipse at 12:31 AM July 5.

We say subtle because, unlike a total lunar eclipse, Earth’s Moon will not change to reddish/coppery colors. The Moon will instead become oddly shadowed for a Full Moon, as it enters the outer fringes of Earth’s shadow in space — the penumbra. Only the “top” portion of Luna will pass through the penumbra making this eclipse especially slight. Still, it’s worth a look and it won’t be at a particularly late hour. A deeper penumbral lunar eclipse will take place the night of November 30, 2020.

While it’s possible to view this eclipse with the unaided eye, binoculars will provide an enhanced view as would a small telescope.

And just in case there’s any confusion, lunar eclipses are perfectly safe to view and photograph — it’s moonlight — so nothing to worry about there.

Our October 5 Open Night was the local event of the International Observe the Moon Night — an annual occurrence meant that encourages observation, appreciation, and understanding of our Moon and its connection to planetary science and exploration. Over the course of the night at Stephens Memorial Observatory some 34 enthusiastic and inquisitive visitors attended and were treated to beautiful and unusual views of Earth’s Moon and planet Saturn.

Unusual? The earliest visitors arrived just as the telescope was set to go … with the sky still bright with twilight. The Moon appeared light and against a power-blue sky background instead of the usual darkness of space. Saturn, invisible to the eye in the bright sky, was also viewed through the telescope in surprising detail.

 

Zooming in on the previous image: That dot in the center of dark-floored crater Alphonsus is its central peak. Over the course of two hours sun rose over that pinnacle making it brighter, and other features began to emerge as we watched. Alphonsus slightly overlaps the crater Ptolemaeus.

After darkness fell enthusiastic visitors took turns looking at a crater and watching a mountain peak become illuminated at sunrise on the Moon! It was a fine night appreciating a sight too often ignored: the wonder of Luna, our nearest neighbor in space.

Save the Date! International Observe the Moon Night will take place on October 5th 2019.

Stephens Memorial Observatory of Hiram College will host a Public Night Saturday, October 5, from 7:00 to 9:00 p.m. Earth’s Moon will be featured as our local participation in International Observe the Moon Night — a worldwide appreciation of Earth’s nearest neighbor in space. As an exciting bonus, planet Saturn will float near Moon in our skies and will also be observed. Other objects may also be viewed. Given good viewing conditions the Observatory’s 1901 vintage telescope delivers outstanding detail of the Moon and impressive views of Saturn with its distinctive rings.

An interesting activity any time of year is to make note of the daily changes we see in the phases of Moon. Open the PDF to print a handy guide and journal for lunar observation: Moon-Observation_Journal.

Cloudy skies at the scheduled starting time cancel the event in which case, the observatory will not open. No reservations are required and there is no admission fee for observatory public nights.

The Observatory is located on Wakefield Road (Rt. 82) less than a quarter of a mile west of Route 700 in Hiram. There is no parking at the Observatory. Visitors may park on permissible side streets near the Post Office, a short distance east of the observatory.

UPDATE: Thanks to the 29 visitors, of a wide variety of ages, who came out Saturday night to share the view with us. Early arrivals got good views of Saturn. In the middle of our evening our guests saw Saturn under improving conditions and the rising Moon as it cleared neighboring trees. Those who visited or stayed late viewed the Full Harvest Moon (sometimes through tree leaves). Our Moon, though fascinating to view through our telescope even when Full or nearly so, created huge amounts of natural light “pollution” as it illuminated atmospheric haze and thin clouds — we were unable to see the Great Andromeda Galaxy or the M15 star cluster. The Moon got tangled in trees again as it arced higher into the sky. Our final visitors of the evening, however, were rewarded for their patience with views of the Perseus Double Cluster after it cleared trees. We love trees but not so close to the observatory!

Stephens Memorial Observatory of Hiram College will host a Public Night Saturday, September 14, from 9:00 to 11:00 PM. On the observing list are: Earth’s Moon, Saturn, the Messier 15 star cluster, and, if sky conditions permit, the Andromeda Galaxy, and Perseus Double star cluster. Given good viewing conditions the Observatory’s 1901 vintage telescope delivers outstanding detail of the Moon and impressive views of Saturn and distinctive rings.

Cloudy skies at the scheduled starting time cancel the event in which case, the observatory will not open. No reservations are required and there is no admission fee for observatory public nights.

WRAP-UP: We played peek-a-boo through clouds with Moon and Jupiter all evening. When they first became visible from behind neighboring trees, viewing of our Moon and the planet was fair to poor. As time passed and the atmosphere settled down, seeing became better and late visitors were treated to excellent views of Moon and fair to good views of Jupiter with his four Galilean Moons and even the Great Red Spot (GRS). In fact, just before we closed for the night, the GRS showed not just as a thickening in the Southern Equatorial Band but as a definite shape with red coloration! Saturday’s was not the best view we’ve had of Jupiter but in the end, it was pretty good. Thanks to the 34 visitors who came out on a muggy and buggy night to enjoy the sights!

Stephens Memorial Observatory of Hiram College will host a Public Night Saturday, July 13, from 9:30 to 11:00 PM. On the observing list are two Stephens favorites: Earth’s Moon, and planet Jupiter with its moons. Other objects of interest may also be viewed using the Observatory’s 1901 vintage telescope. Given good viewing conditions, organizers say, the telescope delivers outstanding detail of the Moon and impressive views of Jupiter including, when it’s in position as it will be July 13, the planet’s Great Red Spot feature.

Organizers hope for clear skies since recent weather conditions have made scheduled observing impossible.

2007 Total Lunar Eclipse

Exciting News: A total lunar eclipse will take place January 20 – 21 and our area will be able to view the entire event, IF we are fortunate enough to have clear skies!

On the night of January 20, 2019 Earth’s shadow will cross the face of its Moon and viewers across North America will be treated to a total lunar eclipse. We, in Northeastern Ohio, are in luck this time as the entire eclipse will be visible to us given clear enough skies, of course.

As the penumbral phase of the eclipse begins, at 9:36 PM, viewers will see the Full Moon gradually dimming, entering the lighter outer portion of Earth’s shadow. At 10:33 the partial eclipse begins and the disk of the Moon will show a dark, curved area expanding across its area. As the Moon moves deeper into shadow it will continue to darken until begin to glow a copper-red until at totality,11:41 PM, Luna will hang colorfully in our star-sprinkled sky as totality begins — the time the Moon is fully within the darkest portion of Earth’s shadow, known as the umbra. Maximum eclipse takes place at 12:12 AM (Jan. 21) and totality ends at 12:43 AM. As the eclipse ends, the process reverses until in the wee hours of Monday, the Full Moon will brightly shine again.

Please note: Because Stephens Memorial Observatory is located in a residential area and the peak portion of the eclipse will take place late at night, the observatory WILL NOT be open. Our big telescope is not necessary for your enjoyment of this wondrous natural phenomenon however, just go outside and look up! Binoculars or a small telescope may give a more detailed view but are not necessary. A lunar eclipse is completely safe to watch — it’s moonlight — so you need no special glasses or vision protection.

CANCELED: Skies will remain cloudy through Saturday and into Sunday with a chance of snow showers. Also, streets in Hiram Village have been stripped for resurfacing and present challenges to parking. We can’t catch a break this year, it seems. Tonight’s scheduled Open Night is CANCELED and the observatory WILL NOT be open. — Saturday, Nov. 17.

UPDATE: It appears that, yet again, we will need to cancel our scheduled Open Night event due to sky conditions and weather! We will post a final update here Saturday afternoon regarding the status of the evening’s event. — Friday, Nov. 16.

Stephens Memorial Observatory of Hiram College will host a Public Night Saturday, November 17, from 7:00 to 9:00 PM. On the observing list are the Moon, the Pleiades and Perseus Double star clusters, a farewell look at Mars, and a possible peek at planet Neptune. Other objects of interest may also be viewed.

Organizers hope for clear skies since several recent events have been canceled or compromised by weather. Visitors will be able to view planetary and celestial objects using the Observatory’s 1901 vintage telescope as well as stunning views of Earth’s Moon.

Cloudy skies at the scheduled starting time cancel the event and in that case, the observatory will not open. No reservations are required and there is no admission fee for observatory public nights.
