A free program on the "Great American Eclipse" presented by Bob Scott, president of the Island County Astronomical Society. On August 21, 2017, the Earth will cross the shadow of the moon, creating a total solar eclipse. Eclipses happen about every six months, but this one is special. For the first time in almost 40 years, the path of the moon's shadow passes through the continental United States. Learn more from Bob about the solar eclipse - what causes it, history and facts, and the where, when and how to safely view it.
