Experience The Eclipse

August 21, 2017
8:30 a.m. – 6 p.m.

This summer, witness a solar eclipse, a truly astounding celestial event, at the epicenter of science in Seattle: Pacific Science Center.

A total solar eclipse is a unique phenomenon that hasn’t happened in the contiguous United States since February 26, 1979. During a total solar eclipse, the Sun is entirely blocked by the Moon, and in totality, night appears in the middle of the day and temperatures drop.

While Seattle is not on the path of totality we will experience a partial eclipse with over 92% of the Sun blocked, still an impressive event.

On August 21, Pacific Science Center will open at 8:30 a.m.* to prepare guests for the eclipse that will begin at 9:08 a.m. The maximum of the eclipse will be at 10:20 a.m. and it will end at 11:38 a.m.

The first 800 paying guests (including both Members who receive free admission and non-Members) will receive a pair of eclipse glasses. We welcome more than the first 800 guests to enjoy the eclipse with us that day and encourage guests to bring their own eclipse glasses or eclipse viewers.

Along with solar telescopes and safe viewing glasses, the Science Center will also have hands-on activities, demonstrations, and conversations about solar eclipses, the Sun and our sky.

We will also be live streaming the eclipse from a totality site and projecting those enlarged images for guests to see.

Activities include:

  • View the eclipse through safe viewing glasses.
  • Talk with our education staff about eclipses and see hands-on demonstrations about how eclipses occur.
  • In the event of clouds (always possible in Seattle!) view the eclipse as it’s live streamed from other clear weather locations.

Activities and viewing of the total solar eclipse is included with admission and FREE for Pacific Science Center Members.

Want to see the eclipse in its totality? Attend the Lowell Solar Eclipse Experience in Madras, Oregon sponsored by Lowell Observatory. Learn More
