Until further notice we are doing all meetings and events online using Zoom.
Located in Flagstaff, AZ, the CAS draws expert program speakers from many sources, including Lowell Observatory, the U.S. Geological Survey, the Naval Observatory, Northern Arizona University, Coconino Community College, as well as organizations in AZ, NJ, CA, NY and our own knowledgeable membership, and occasionally from other astronomical groups.
