Viewing the Partial Solar Eclipse in Colorado

Please note, we’ll be updating this list as we find more opportunities. If you know of an event that isn’t listed here, please email

On Thursday, October 23, a partial solar eclipse will be visible throughout Colorado, beginning at 3:18 p.m. and ending at 5:44 p.m. Partial solar eclipses occur when the moon blocks part of the Sun from view. During Thursday’s eclipse, about half of the Sun will be hidden from view.

Here are some ways that you can experience the eclipse in Colorado:


Zacheis Planetarium (NOT the observatory!) between 3:30 p.m. and 5:30 p.m. will have safe eclipse viewing glasses you can use, telescopes you can look through, and a projection of the Sun’s image so lots of people can look at once. Free.

Fiske Planetarium is selling protective glasses to the public for $2.50 before Thursday or $5 on the day of the partial eclipse.
