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 eclipses without hurting your eyes, wherever you are.   (For more about Andrew Fraknoi and his educational outreach work, see: http://fraknoi.com )
