Great American Total Solar Eclipse August 21, 2017

  • PLEASE NOTE: We regret to inform you that we no longer have eclipse glasses for sale, either online or in our store. However, to learn how to build an eclipse viewer, please scroll below. Thank-you so much for supporting the Clark Planetarium, and may you enjoy a safe and happy eclipse.

    Clark Planetarium will be at the Salt Lake City Main Library, Wheeler Farm, and The Gateway Plaza Fountains during the entirety of the eclipse, from 9:30 AM to 12:30 PM. 

    On August 21st, 2017, the United States will experience a total eclipse of the Sun that stretches from Oregon to South Carolina. Multiple states, many within a day’s driving distance of Salt Lake City, Utah, will experience totality, where the Sun is completely blocked out by Earth’s Moon. While Salt Lake City will not experience totality, the city will see 91% coverage, a marvelous spectacle. 

    The following two short videos will help you 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.



    Also,  National Geographic has 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 will occur 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 AM
    Eclipse end time: 12:59 PM

  • Safe Viewing of the Eclipse

    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.

    Safety Don'ts for the Eclipse

    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”
