August 21 — The 2017 Total Solar Eclipse

While the path of August’s total solar eclipse will pass across the United States hundreds of miles north of Los Angeles, a partial solar eclipse will be visible from Los Angeles.  Mount Wilson Observatory, which was the leading center for solar research during the first half of the twentieth century, will celebrate the event with free public viewing through a variety of solar telescopes. The eclipse will begin in our area at 9:05 a.m. Maximum eclipse will occur at 10:21 a.m., with the Moon covering about 70% of the Sun’s diameter and 62% of its area. The eclipse will end at 11:44 a.m.
