David will talk about eclipses in general and the annular solar eclipse which will occur here in Nevada County on Sunday afternoon May 20th. He will discuss what to look for, and how to observe and photograph the eclipse. Several of David's eclipse photos have been published in Astronomy magazine. In addition. he will also introduce listeners to a rare event happening just two weeks after the eclipse - a transit of Venus. We are lucky to be on the west coast for both of these events and the transit is the last one in our lifetime.

Venus has a storied history - one with an amazing history of hardship, long voyages, and including some with hard luck in observing the transit of 1769, which was critical in determining the distance to the Sun - the Astronomical Unit

Guests are always welcome. Bring a friend.
