Eclipses – What Is There To See? - St. Louis Astronomical Society Meeting

Eclipses – What Is There To See? - St. Louis Astronomical Society Meeting

An illustrated live and virtual presentation by Vivian White of the Astronomical Society of the Pacific

An eclipse occurs when the light from one astronomical body is blocked by a second astronomical body. An eclipse of the Sun occurs when and where the shadow of the Moon falls upon the Earth. An eclipse of the Moon occurs when the shadow of the Earth falls upon the Moon. An eclipse will be total if the shadow covers the entire body. The eclipse will be partial if only part of the eclipsed body passes inside the shadow. An annular eclipse occurs when the Moon’s shadow is too small to cover the entire solar disk, so that a “ring of fire” results at mid-eclipse. There will be an annular eclipse of the Sun on October 14,2023. The next total solar eclipse will occur on April 8,2024. Vivian White will talk about what kinds of views can be seen and what effects can be noticed during different types of eclipses

 Vivian White has been an astronomy educator with the Astronomical Society of the Pacific for the last decade. She currently designs activities for amateur astronomers engaged in public outreach through the NASA Night Sky Network, a coalition of over 400 astronomy clubs across the US. Her first book, The Total Skywatchers Manual, was released in September 2015.
