PUBLIC EVENTS
The CAA hosts at least 12 Saturday Public Observing events featuring a
guest speaker that is followed—weather permitting—by celestial viewings
through telescopes at the facility. During viewing hours, society members
will be available to answer questions and provide everyone with an
opportunity to look through the Society's telescopes and those of our
members.
This site will be updated through out the year as we assemble our speakers
and events.

Lost Siblings of the Sun
Can we find some of the stars that were formed in the same Star Formation Region as the Sun, 4.5 billion years ago? Incredibly, some sober astronomers think the answer is yes, and published a paper to this effect in the Astrophysical Journal. The star is visible to binoculars and should be up at the time of the March public night.
