AAVSO 111th Annual Meeting

The AAVSO 111th Annual Meeting will be held at The Omni Tucson National Resort in Tucson, Arizona November 4 – 8, 2022.

The organization has announced a call for abstracts and presentations for the meeting.  Those interested in giving an oral presentation or present an online poster at the meeting can submit an abstract through September 4. The AAVSO notes that in-person presenters will be given preference to remote oral presenters. The annual poster hall will be online only this year and in-person poster presentations will not take place.

AAVSO 111th Annual MeetingPresentations will be focused on one of the following topics: Variable star research or history and astronomy education/diversity in astronomy. More information on submitting presentations and posters, including poster examples, can be found here.

During the AAVSO 111th Annual Meeting, the organization begins a new tradition: the Arlo U. Landolt Lecture. As noted by the AAVSO, “This lecture celebrates the memory of Dr. Landolt, who was both a brilliant scientist and a gentleman beloved by the AAVSO community. His lifetime of work has dramatically increased our understanding of the cosmos. The honor of presenting this prestigious lecture will be awarded each year to a prominent astronomer whose research expands upon Dr. Landolt’s accomplishments.”

The 2022 Arlo Landolt Award recipient and guest speaker is Dr. Arne Henden. Dr. Henden received his doctorate from Indiana University, and subsequently worked for Goddard Space Flight Center, The Ohio State University, and the U.S. Naval Observatory as an instrumentation specialist. For the last decade of his career, he served as the director of the AAVSO. He retired to New Hampshire, where he currently runs several automated telescopes. Dr. Henden is the author of a textbook and several hundred scientific articles and has given lectures worldwide.

Dr. Henden will be discussing special elements of the AAVSO Photometric All-Sky Survey (APASS). APASS was started from discussions with Arlo Landolt, and was awarded an NSF grant based on his support of the project. All-sky calibration is necessary for the AAVSO to provide comparison stars for targets of interest, and APASS was designed to meet that goal.

Dr. Henden will highlight the early history of the all-sky calibration project, as well as comparisons with other surveys. He will also announce the status of DR11, the next formal release of APASS. Dr. Henden will then conclude by describing the new XPASS and APASS2 projects, with their all-sky completion and bright-star extension, along with volunteer opportunities for helping with the survey.

In addition to Dr. Henden presentation, the meeting’s keynote speakers include Dr. James Clem, Dr. Liliana Rivera Sandoval, Dr. Misty Bentz and Sean Walker.
