Upcoming Events


The Great American Eclipse of the Sun is coming up on Monday, August 21, 2017

Don’t miss an incredible sight you’ll remember your whole life! On Aug 21, 2017 the best total eclipse of the Sun in 40 years will cross the U.S. Every state (except Alaska and Hawaii) will have at least 75% of the Sun covered by the Moon, and the lucky people in a 70-mile wide strip from Oregon to South Carolina will see an amazing TOTAL eclipse!

Where to watch

The best place to watch is along the path of totality - where the Moon will completely block the Sun. To find locations and driving directions where you can view the total eclipse, we recommend the Totality app by Big Kid Science and the NASA eclipse website.

The second best place to watch is from anywhere with an open sky (no trees directly above or buildings in front of you). You MUST HAVE eclipse glasses to safely watch the partial eclipse (available for sale at Fiske Planetarium, McGuckin Hardware, and the CU bookstore - get them early!) or you can make a pinhole camera - see the “Watch Safely” tab for more details. You can also watch NASA live video from the total eclipse here.

Most of the staff from Fiske Planetarium and Sommers-Bausch Observatory will be where the eclipse is total, recording video and audio. Therefore, we do not have any shows scheduled and the buildings will be closed. However, we will have a few solar telescopes on the lawn outside the Fiske Planetarium front doors staffed by astronomers, and we will have eclipse glasses for sale while supplies last. Note that parking on campus will be extremely limited due to CU move-in.
