The Great American Eclipses of 2023 and 2024

Eclipse Outreach Resources

Get ready to mark your calendars, in October of 2023 and April of 2024, we will witness two solar eclipses crossing America! First, on October 14, 2023, an annular solar eclipse will cross from the Pacific Northwest down through Texas. Later, on April 8, 2024, a total solar eclipse will occur, passing from Texas up through the Northeastern states!

The Eclipse Livestream

Join Sigma Pi Sigma and SPS as we celebrate! Sigma Pi Sigma will be livestreaming the eclipse from multiple locations within the eclipse path, and participating SPS and Sigma Pi Sigma chapters will be contributing live views from their telescopes or video cameras. In 2023, we hope to feature at least 11 locations across the country. SPS and Sigma Pi Sigma chapters can apply for eclipse glasses, applications will open in the summer of 2022.

Participating Chapters

Participating chapters will be eligible for supplies and support for outreach events, as well as training materials for holding their events.
