The sun will undergo an eclipse which will be observable from coast to coast in the United States. A coast to coast eclipse has not occurred for 99 years. Since the moon's orbit is elliptical, the distance between the earth and the moon changes. When the moon is further from the earth during an eclipse, the outer edges of the sun are not obscured by the moon. As a result, we get an annular eclipse. This last occurred in the United States in 1994. During this eclipse the moon will be closer to the earth resulting in totality (the moon completely obscuring the sun).
Cedarville is not in the path of totality, but we will still get an impressive view of the eclipse. At 1:01 the moon will touch the edge of the sun. Over the next 1 1/2 hours the moon will obscure an increasing amount of the sun. At 2:28 88% of the sun will be obscured by the moon. Beyond that time the sun will reappear from behind the moon until 3:50 when the eclipse will be over.
We hope to have clear skies (so far the weather forecast is hopeful). On the south end of the ENS building several telescopes will be set up with solar filters. The observatory will also be open providing a screen projection of the sun from one of the sighting telescopes. Eclipse glasses will be available for use at the event. Hope to see you there.
