The Minnesota Astronomical Society would like to invite you to attend the Astronomical League’s Fall Astronomy Day activities at the MAS Eagle Lake Observatory in Baylor Regional Park. Speakers are scheduled throughout the day and will give talks on astronomy and what there is to see. Door prize drawings will be held Saturday evening and include MAS merchandise, astronomy books and videos. Weather permitting, the evening will conclude with tours of the night sky and of course stargazing.

Schedule of Events – Subject to Change

Saturday October 5, 2019

The observatory will open at 1:00 pm for some solar viewing as well as other bright daytime objects. Venus and Mercury will be visible in the afternoon. Jupiter, The Moon, Saturn, and Neptune after sunset We may even see the Dwarf Planet Ceres and a comet or two. In the evening we’ll have some of the late Summer & Fall objects coming into view including the Swan nebula, Ring nebula, the Dumbbell nebula, the Wild Duck cluster, the Whirlpool galaxy, the Hercules Cluster, and Andromeda galaxy among many others.

Scheduled Speakers


Speaker: Colin Kilbane

Topic: “Mad Scientist” presentation, with fascinating science demonstrations of chemical reactions, bubbling potions and more.


Speaker: Sarah Weaver

Topic: Talking Science-Engaging the public one person at a time.


Speaker: Sarah Komperud

Topic: Astronomy at the Bell Museum has moved beyond just the planetarium. Telescope observing, a Saturday morning youth program, special exhibits, events, and PreK-12 lab experiences all augment the planetarium and permanent Life in the Universe exhibit. What’s more – we’re pushing the planetarium to do more than ever before with new, never before seen content. Astronomy is for everyone. Come ignite your curiosity and wonder, explore our connections to nature and the universe, and help us create a better future for our evolving world.


Dinner Break


Speaker: Parke Kunkle

Topic: Precession: What is it? Why is Polaris the current north star? What does this have to do with the zodiac?
Parke will define and demonstrate precession, relate it to Earth’s motion, discuss our past, current and future north stars. As time permits, he will demonstrate where our Sun actually is in the zodiac.


Door Prize Drawing – Must be present to win.


Tour of the Sky on the Plaza: We will conduct a laser pointer tour of the constellations from the plaza in front of the Onan Observatory. (If it is cloudy there will be a presentation in the classroom)

Evening Activities

The evening will continue with viewing through our array of telescopes. We bid farewell to the best summer constellations, nebula and clusters and enjoy the arrival of some of the fall and winters best while the Minnesota temperatures are still “balmy”.

Eagle Lake Observatory

Consisting of the Onan Observatory, the Sylvia A. Casby Observatory and the HotSpot Classroom, the MAS’ Eagle Lake Observatory is the regions premier all-volunteer public observing facility.

  • Two observatories with more than a dozen of the finest amateur telescopes available to view through.
  • Real-time video viewing capabilities for lunar, planetary and deep-sky viewing.
  • Solar filters allow safe viewing of the Sun’s surface, sunspots and solar prominences.
  • Mounted 15×80 binoculars for the ultimate “wide-field” stargazing experience.
  • A heated classroom to take the chill out of the cool fall nights.
  • Electrical outlets on the outside of the buildings for those who bring their own scopes.
  • Paved handicap parking adjacent to the wheelchair accessible observatory.

Baylor Regional Park is roughly 25 miles southwest of the Eden Prairie, MN and just north of Norwood-Young America. It is easily reached either by Minnesota Highway 5 or U.S. Highway 212. Click HERE for interactive map.

Event Cost

There is no charge to attend a public star party, however, Baylor Park will charge $6 for daily parking. If you have a Carver County Park sticker, this fee is of course waived. To help us maintain the observatory, purchase door prizes and to pay the bills, donations to the MAS are also welcome.

Astronomy Day

The theme of Astronomy Day is “Bringing Astronomy to the People”. This worldwide event invites astronomical societies, planetariums, museums, and observatories to sponsor public viewing sessions, presentations, workshops, and other activities to increase public awareness about astronomy and our wonderful universe.

Astronomy Day was born in California in 1973. Doug Berger, then president of the Astronomical Association of Northern California, decided that rather than try to entice people to travel long distances to visit observatory open houses, they would set up telescopes closer to where the people were – busy locations – urban locations like street corners, shopping malls, parks, etc.

His strategy paid off. Not only did Astronomy Day go over with a bang, not only did the public find out about the astronomy club, they found out about future observatory open houses. Since the public got a chance to look through a portable telescope, they were hooked. They then wanted to see what went on at the bigger telescopes, so they turned out in droves at the next observatory open house.
