Star Parties in the Era of COVID

Like everyone else, our plans have been interrupted by the COVID-19 pandemic.  We plan to follow the direction of the government and advice of public health professionals and UIS Campus guest pandemic guidelines. to decide what we cancel.  It is very important to us also that our volunteers feel comfortable helping with the event.  To comply with those guidelines we are going to replace in-person star parties with virtual events.

There is a silver lining to this.  A virtual Star Party lets us share things with you that we could not for an in person Star Party.  We are planning to go live for many of them from the research observatory.  When the weather cooperates we will share views with cameras through the 20-inch telescope and of the dark night sky.

When the weather does not cooperate… well no problem.  This is another advantage of the virtual Star Party: we will do it whether clear or cloudy.

So please plan on joining us virtually on Friday nights this fall.

Fundraising for a New Deck

Someday we hope to resume in-person Star Parties.  We built a new deck we hope to show off when we can all get together in-person.  We are continuing to fundraise for disability upgrades and replacing the telescope enclosure.

For information about our efforts to renovate the UIS Campus Observatory used for Star Parties, please follow this link.

What is a Star Party?

Since 1980, thousands of people of all ages have come to the UIS observatory for Friday Night Star Parties, as well as for special astronomical events such as lunar and solar eclipses and comets.

At a typical Star Party, vImage taken from hubblesite.orgisitors learn about galaxies, the sun, stars,
and stellar evolution, as well as star and constellation identification
prior to using the telescopes. These discussions take place in the stairway
gallery of astronomical pictures on the way to the rooftop observation
deck atop Brookens Library. Then, the observatory director and qualified
volunteers help visitors use each of the telescopes.

Over the years, stargazers have seen many celestial objects, including the moon and planets, deep-sky objects such as the Orion Nebula and other fascinating star systems, the beautiful yellow-blue double star Albireo, and the open star cluster called the Pleiades.

The Astronomy Program also offers Sunday Night Star Parties for people who are challenged by stairs and ladders and their friends and families.

How do I get more information?

For general questions about Friday Night Star Parties call 217-206-8342.

Or check out Twitter feed @UISObservatory.

What do you do if it is cloudy?

This is NOT a thing for virtual Star Parties in Fall 2021.  For virtual Star Parties we will do them regardless of clouds in the sky.

When we are back to in person Star Parties, in order to learn if the weather is suitable for viewing, please call 217-206-8342 after 7:00 PM on the night of the Star Party.

Or you can get information on when the observatory is open from our twitter feed.

Is there elevator access to the Campus Observatory for a Friday Night Star Parties?

Again, not an issue for virtual Star Parties in Fall 2021.

For in person Star Parties at the campus observatory: No. Not during a Friday Night Star Party. Visitors to a Friday Night Star Party must be able to climb up and down four flights of stairs AND climb a short 5 ft ladder up to the main telescope dome. If you or a loved one that wants to attend a Star Party has trouble with stairs or ladders you should call 217-206-8342 and ask about our Sunday Night Star Parties for people with disabilities. Those Star Parties are fully accessible and require no stair or ladder climbing.

Are regular Friday Star Parties accessible in 2021?

Sorry but accessible Star Parties are canceled until the University lifts restrictions in place for COVID.

But if you are interested and you want to attend an accessible Star Party sometime in the future you are encouraged to express your interest.  Please contact John Martin (217-206-83442) about Sunday Night accessible Star Parties.

Where is the UIS Campus Observatory?

The Campus observatory will be closed until the University lifts restrictions in place for COVID.

The Campus observatory is on the roof of Brookens Library. The door for the observatory is on the southeast corner of the library (side opposite the UIS fountain) and the door is marked “Observatory.” You have got to go all the way round the corner to see the observatory door. The observatory is through that door and up five flights of stairs to the roof. We appologize for the deplorable lack of signage. We are working on it. On that map below the library is building #7 and the door for the observatory is on the lower right corner of the outline of the building. Map to Campus Observatory
