Listen to exciting, non-technical talks on some of the most interesting developments in astronomy and space science. Founded in 1999, the Silicon Valley Astronomy Lectures are presented on six Wednesday evenings during each school year at Foothill College, in the heart of California's Silicon Valley. Speakers include a wide range of noted scientists, explaining astronomical developments in everyday language. The series is organized and moderated by Foothill's astronomy instructor emeritus Andrew Fraknoi and jointly sponsored by the Foothill College Physical Science, Math, and Engineering Division, the SETI Institute, the Astronomical Society of the Pacific, and the University of California Observatories (including the Lick Observatory.)

episode 5: An Eclipse Double-Header: Two North American Eclipses of the Sun in 2023 & 2024 (with Andrew Fraknoi)
North America will be treated to two eclipses of the Sun in the 2023-24 school year: an annular eclipse on Oct. 14, 2023 and a total eclipse on Apr. 8, 2024. Some 500 million people will be in a position to see at least a partial eclipse on each date. Astronomer Andrew Fraknoi (Fromm Institute, University of San Francisco) discusses the cause of eclipses (and why Earth's eclipses are unique), the circumstances of each coming eclipse and where each will be visible, plus how to view eclipses safely. He shows maps of the eclipse paths and provides URLs to where you can get free information materials to help you enjoy the eclipses without hurting your eyes, wherever you are. (A free booklet, co-authored by Fraknoi, with some of this material is also available at http://bit.ly/eclipsesforlibraries )
