The Great American Eclipse of the Sun occured on Monday, August 21, 2017.

 

Where we watched

The best place to watch was along the path of totality - where the Moon completely blocked the Sun. To look back at locations and driving directions where one could view the total eclipse, we recommend the Totality app by Big Kid Science and the NASA eclipse website.

The second best place to watch was from anywhere with an open sky (no trees directly above or buildings in front of you). You MUST HAVE had eclipse glasses to safely watch the partial eclipse (Fiske Planetarium-Sold out!, McGuckin Hardware-Sold out!, and the CU bookstore-Sold out!) or you could have made a pinhole camera - see the “Watch Safely” tab for more details. You could have also watched NASA live video from the total eclipse here.

Most of the staff from Fiske Planetarium and Sommers-Bausch Observatory traveled to where the eclipse was total, recording video and audio. Therefore, we did not have any shows scheduled and the buildings were closed. However, we did have a few solar telescopes on the lawn outside the Fiske Planetarium front doors staffed by astronomers. Doug Duncan wearing eclipse glasses


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!

I’m Dr. Doug Duncan, CU Astronomer and Fiske Planetarium Director. I’ve been studying the sun, stars like the sun, and chasing eclipses for over 40 years.  A partial eclipse is interesting to watch.  If you protect your eyes you can see the moon take a big bite out of the sun. The total eclipse is much, much more spectacular.  It looks like the end of the world, with loops of hot gas –prominences – leaping off the edge of the sun, and big silver streamers of the sun’s corona stretching across the sky. It gets dark and cold - there's a black hole in the sky where the sun should be. People cry, scream, shout, and celebrate. Animals do strange things. If you can travel to where the eclipse is total – do it!
