Andrew Fraknoi: Two Eclipses of the Sun

Andrew Fraknoi

Two eclipses of the sun are coming to North America during the 2023 - 24 school year - an annular (“ring of fire”) eclipse on October 14, 2023 and a total eclipse on April 8, 2024. People in two narrow paths will have the full eclipse experience each time. Everyone else (an estimated 500 million people, including all of us in the Bay Area) will see a nice partial eclipse, where the moon covers a good part of the sun.

Andrew Fraknoi will describe how eclipses come to be (and why they are total only on Earth), what scientists learn during eclipses, exactly when and where the eclipses of 2023 and 2024 will be best visible, and how to observe the eclipses and the sun safely.

Everyone who attends this program in person will receive a free pair of safe-viewing glasses for the eclipse (which enable you to look at the sun without eye damage), courtesy of the Gordon and Betty Moore Foundation.

Speaker: Andrew Fraknoi, Foothill College, Emeritus
