In our first Safety 101 blog, we talked about the importance of viewing the solar eclipse safely, and as the eclipse covers most of North America, on Monday August 21, we want to make sure viewers know exactly how to view this rare phenomenon.

To safely view the solar eclipse, follow these guidelines:

  • Stand still and cover your eyes with eclipse glasses or solar viewers before looking at the uneclipsed or partial eclipsed sun.
  • Do not remove solar filters while viewing the uneclipsed or partial eclipsed sun. Only remove the filters after you are done glancing at the sun.
  • If you are within the path of totality, only remove solar filters when the moon completely covers the sun.
  • As soon as totality is over, replace eclipse glasses or solar viewers and glance at the remaining partial eclipse.

As a reminder, do not look at the uneclipsed or partial eclipsed sun through unfiltered cameras, telescopes, binoculars, or other optical devices, even if you’re wearing eclipse glasses or solar viewers.

Solar eclipses are a once-in-a-lifetime event, but viewing one without following the proper safety guidelines is not safe. So be sure to follow these guidelines and read the instructions printed on your approved solar filters and eclipse glasses.
