2021 General Meetings & Special Events

Until further notice we are doing all meetings and events online using Zoom.

A Zoom link is being included with the email notice sent out for the meeting. . The same link is being used for all meetings until further notice. You do not need a Zoom account to join this meeting.

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. CAS also helps schools near the Navajo reservation, as well as the Hopi with their astronomical programs.

CAS Monthly Meetings and Astronomical Programs are held the Saturday closest to the Full Moon at the Mars Hill Campus of Lowell Observatory, Hendricks Center for Planetary Studies Auditorium (6:45 pm - 8:00 pm., unless otherwise noted) followed by refreshments, and informal discussion. Meetings are open free to the public.


Online Zoom Meeting

Saturday, January 30, 2021
Barry D. Malpas, CAS VP

Title: “Meteor Impact Craters around the World and Near Earth Asteroids”

Barry Malpas is currently CAS VP and teaches astronomy at CCC. Mr. Malpas contributes monthly astronomy articles to the Williams-Grand Canyon News and is also a collector of meteorites. He is a past-President of Amateur Astronomers, Inc, Union County College, Cranford, NJ, and past Founder and Director of UACNJ Observatory, Jenny Jump State Park, Hope, NJ.


Online Zoom Meeting

Saturday, February 27, 2021
John W. Briggs, Director of the Astronomical Lyceum Magdalena, NM

Title: “Walking Tour of Optical History - Artifacts and Anecdotes from the Astronomical Lyceum”

Our forefathers in optics allowed a revolutionary ascendancy of American astronomy in the 19th and early 20th centuries. The Astronomical Lyceum in New Mexico, originally built in 1936 as a theater and gymnasium, now houses a collection of telescopes, optics, archives, and literature from this ascendancy. The presentation will include unusual items, large and small, created by some of the America's greatest early optical artists, including Henry and Harry Fitz, Alvan Clark and Sons, Carl and Robert Lundin, John A. Brashear, George Willis Ritchey, and the pioneer of astronomical spectroscopy and photography, Lewis Morris Rutherfurd.


Online Zoom Meeting

Saturday, March 27, 2021
Dr. Klaus Brasch, past CAS VP

Title: “A Lifetime of Astronomy”

Dr. Brasch joined the Royal Astronomical Society of Canada with the launch of Sputnik 1 in 1957 and has remained actively engaged ever since. The hobby has changed greatly since then, when most people built their own telescopes and “observing” was done mostly by eye not photographically. It was also a golden era of amateur astronomy, because direct exploration of the solar system, manned spaceflight and the race to the Moon still lay ahead, and dedicated amateurs with modest size telescopes could meaningfully participate in the grand adventure to come. Klaus will trace this progression through 63 years of personal involvement.

Dr. Brasch’s astronomical images and articles have widely been published in popular books and magazines, including Sky & Telescope, Sky News, Astronomy Technology Today, the Journal of the British Astronomical Association and the Journal of the Royal Astronomical Society of Canada. He has also translated several French books into English, including Urban Astronomy, Great Observatories of the World, New Atlas of the Moon and Space Probes, for Oxford University Press and Firefly Books.


Online Zoom Meeting

Saturday, April 24, 2021
Emily Mailhot

Title: “Adaptive Optics at Las Campanas Observatory”

During "Adaptive Optics at Las Campanas Observatory" we'll learn about how our pesky atmosphere causes poor seeing, adaptive optics basics, and how adaptive optics can emulate having a telescope in space from the ground. We'll also touch on how astronomers travel to remote observatories like Las Campanas in the Atacama Desert, Chile.

Emily Mailhot is an Observational Specialist for the University of Arizona’s Steward Observatory. She holds a B.S. in Astrophysics from Lehigh University. Since 2019 she has been operating the adaptive secondary mirrors on the Large Binocular Telescope and the Las Campanas Observatory Clay and Baade Telescopes. When she isn’t observing she is a flight instructor and road cyclist.


Online Zoom Meeting

Saturday, May 22, 2021
Dr. Nicholas Moskovitz a planetary astronomer at Lowell Observatory

Title: “The essential role of telescopes large and small in NASA's DART mission”

In 2022 NASA will conduct the first-ever planetary defense experiment by impacting a spacecraft into a binary asteroid called Didymos. The Double Asteroid Redirection Test (DART) spacecraft will impact the smaller body in the binary system and aim to change its orbital period about the primary by at least 75 seconds. This will test the efficacy of a kinetic impactor in deflecting the orbit of an asteroid. As the main spacecraft will not survive this encounter, studying the outcome will rely on ground-based telescopes. I will present results of pre-launch observations that have leveraged the 4.3-m Lowell Discovery Telescope, as well as the need for post-impact observations in October 2022 when Didymos will have an apparent magnitude of V~15 and thus be within reach for 1-m class telescopes.

Dr. Nicholas Moskovitz is a planetary astronomer at Lowell Observatory. His work focuses on small bodies -- asteroids, comets, meteors -- in the Solar System. He has degrees from the University of California, Santa Barbara (BS) and the University of Hawaii (Ph.D.).

Williams Public Observing

Due to the Croonavirus Williams Public Observing has been cancelled until further notice

On the Friday evening closest to First Quarter Moon, April through October, CAS hosts its monthly community outreach program to educate and promote interest in Astronomy to the general public.

CAS members set up their telescopes at Glassburn Park in Williams, and invite the public free of charge to observe the Moon and other visible objects in the night sky

Directions for Williams

Location:Glassburn Park - in the natural area west of Rod’s Steakhouse parking lot.
Take I40 west. Exit 165 into Williams. The park is about 2-3 blocks after the hill, just past the edge of town on the right.
