PLEASE NOTE: A big thank-you to all our friends and patrons for your involvement in the 2017 Great American Solar Eclipse. Please visit our blog for other fascinating upcoming astronomical events.
The next solar eclipse visible from Utah will be the annular eclipse of October 14th, 2023. An annular eclipse is similar to a total eclipse, except that the moon appears smaller than the sun and therefore doesn't completely block it out, resulting in a the ring of the sun around the dark disk of the moon. The next total solar eclipse that will pass through the United States will be on April 8, 2024.
We hope you had a happy eclipse!
On August 21st, 2017, the United States experienced a total eclipse of the Sun that stretched from Oregon to South Carolina. Multiple states, many within a day’s driving distance of Salt Lake City, Utah, experienced totality, where the Sun was completely blocked out by Earth’s Moon. While Salt Lake City did not experience totality, the city saw 91% coverage, which was a marvelous spectacle.
The following two short videos were prepared to help people prepare for the August 21st total eclipse. Clark Planetarium gratefully acknowledges the generous contribution of time, equipment and talent by KUTV Channel 2 in making these videos.
National Geographic produced a terrific video where you can learn all about eclipses and how to view them. You can view it here:
The nearest totality to Salt Lake City, Utah occurred in Driggs, Idaho, approximately 4 hours north of Salt Lake City.
Date: Monday, August 21st, 2017
Eclipse start time: 10:13 AM
Maximum coverage in SLC: 11:33 AMEclipse end time: 12:59 PM
There are two safe ways to look at the Sun, whether partially eclipsed or not. You should never look directly at the Sun without the assistance of either:
• Special solar filters, including solar glasses, which must be marked ISO 12312-2• A large piece of welder’s glass, number 14.
You can also safely view the eclipse indirectly with the use of an eclipse projection box.
However you decide to view the eclipse, please:
• DO NOT look directly at the Sun• DO NOT look at the Sun through an unfiltered camera or telescope• DO NOT use sunglasses as a substitute for solar glasses or filters• DO NOT use untested or “new” methods for projection viewers; this includes the newly popular “Pringles Can”

SIMPLEThese projects require a few seconds of effort during an eclipse, but make sure that you set up your activities in the hour prior to maximum eclipse!
ADVANCEDThese activities require a little bit more know-how, and data that you can gather about a past eclipse, or after the August 21, 2017 eclipse has passed.
EXPERTIf you're a veteran of total solar eclipses, these are the activities for you. Requiring a significant amount of scientific work, setting up these experiments will help you to collect data throughout the entirety of an eclipse event.
