2017 Great American Eclipse Event

August 19, 2017 @ 10:00 am - August 21, 2017 @ 5:00 pm


This event is sold out. Only registered guests will be welcomed on camp property during the event.

**This event is designed for individual adults and families.  School groups should contact camp directly about viewing opportunities: 618-695-2489**

On August 21, 2017, Camp Ondessonk will be perfectly positioned to observe a total eclipse of the Sun.  For about two and a half minutes, the sun will be completely blocked from view by the shadow of the moon.  That’s two and a half minutes of eerie daytime darkness.  But the total time between when the eclipse begins and ends completely is closer to 3 hours.  Stars and planets will be visible in the sky, and you will be able to see the Corona (the outer atmosphere) of the sun with an unaided eye.  This will be quite an experience, and one that typically happens only once in a lifetime.

Camp Ondessonk will be hosting an Eclipse Viewing Event August 19-21.  Everyone is welcome for to join us for this unique experience.  We’ll have typical camp activities like swimming, hiking and trail rides available as well as educational sessions put on by amateur and professional astronomers.  Then on Monday we’ll have the opportunity to be at camp to witness the main event.  The event will begin with dinner and Mass on Saturday night and will conclude Monday afternoon.  This is certainly an event worth missing school for!  We hope to see you all there!

This event is open to all ages and levels.  Register by August 1st, 2017 by filling out the following: Eclipse Program Information and Registration

A Premium Package will offer additional access to our keynote speaker and presenters, including a meet-and-greet reception with food and beverages provided.  Premium package participants will also have a private session with local astronomers and access to nighttime telescope viewing.
