The Speakers Bureau is a service established for people and groups looking for enthusiastic, knowledgeable speakers to provide informative presentations for astronomy clubs, star parties, banquets, Scout Troops, Astronomy Day activities and other public and private astronomy functions. Contact us if you are interested in securing a speaker or becoming one yourself.
NOTE: Many of our speakers are willing and able to do remote talks via Skype or other VOIP applications. This allows us to serve more clubs and functions, and minimizes the costs and travel time involved in giving presentations.
Below is a list of our speakers and the geographic areas they serve.
Plymouth, MN (western suburb of Minneapolis), 50 miles
Basic astronomy, observing with small telescopes, variable stars, amateur telescope making
Tom Bretl (home page) is a retired high school math, physics, and astronomy teacher. He has been interested in amateur astronomy since the days of Sputnik, and he has been an active variable star observer since joining the AAVSO in 1975. He wrote a monthly column for Astronomy during the first few years of that magazine's existence, and was an amateur telescope maker during the 1970's. Tom has also developed numerous computer programs designed to encourage his students to explore relationships, discover patterns, and solve problems.
Arch Cape, OR (100 miles)
Variable Star Observing (both Visual and CCD); Choosing a CCD Camera for Science; Roll-Off Roof Construction vs. Dome Construction (w/building hints for both); Why We Can't See Colors in DSO's & The Importance of Averted Vision.
Tim Crawford's Bio and a listing of "published" articles as well as recent presentations can be found at his home page. While the 100 mile travel radius from Arrch Cape, OR is pretty much limited to the Northern Oregon coastal zone and the Portland, OR metropolitan area, I am willing to consider the Seattle, WA area upon request. Travel outside of these zones might require overnight lodging, in addition to travel expenses and meals. Please feel "free" to inquire regarding whatever your groups needs might be. Remember: "There is no such thing as a dumb question."

Originally from Michigan's Upper Peninsula, Albert Holm received his bachelor's degree from Caltech and his Ph.D. from the University of Wisconsin-Madison. He has worked on space astronomy missions since 1970, first with the Orbiting Astronomical Observatory-2, then with the International Ultraviolet Explorer, and finally with the Hubble Space Telescope. Currently retired, he last served as Branch Chief for Data Processing and Archival Services at the Space Telescope Science Institute in Baltimore. He carried out research on cataclysmic variables, R CrB stars, and planetary nebulae. You can find descriptions of some of his presentations at http://www.albertholm.com/AstronomyOutreach.html
Pasadena, CA (100 miles)
Variable Stars for Beginners
Katherine Hutton has joined the AAVSO twice: once in 1967, and once in 2006. She left variable stars once, to earn a PhD in astronomy (specialty in very long baseline radio interferometry) & travel a circuitous academic route into seismology, where she now earns her living processing earthquake data & sharing it with the general public through the TV news, following any large shake-ups. Eventually, the variable stars called her back, however. She is primarily a visual observer, just starting to teach herself CCD photometry & she participates in the Arne's Star program, which allows AAVSO members to help the Director clear his desk of unanalyzed data. Her special interests include semiregular variables, the supergiants & Wolf-Rayet stars. She is a mentor for new visual observers. She has written pieces for the Eyepiece Views newsletter & some content for the AAVSO web site. She is also in training to be a docent for the Mt. Wilson Observatory.

Variable stars and any astronomy related subjects
Roger Kolman has been an active member of the AAVSO since 1962 and was a member of Council in 1999. He holds a Ph.D. in physics from the University of Illinois. He has taught physics, mathematics and astronomy at the secondary and college levels for 39 years and teacher education at the graduate level. Currently he teaches astronomy at Harper College in Palatine, Illinois.
In addition to his teaching duties, he was a mentor for the Teachers for Chicago program in which individuals holding non-teaching degrees were brought into education as a career change.
For many years he has been involved with the Astronomical League serving as Vice Chairman and Chairman of the North-Central Region of that organization. He served a term as Secretary of the Astronomical League and for several years was in charge of the Member-At-Large section of the A.L. Since 1980 he has been the chairman of the Leslie C. Peltier Award Committee. He is the author of Observe and Understand Variable Stars which he wrote as a vehicle for attracting new observers to the AAVSO.
He has spoken before many groups on Variable Stars and other astronomical topics.
Gloucester, MA (100 miles)

Variable Stars, Visual Observing, Stellar Evolution, Cataclysmic Variables, History of the AAVSO
Mike is one of the world’s leading variable star observers and advocates. Since 1998 he has submitted over 88,000 variable star observations to the AAVSO International Database.
Mike is currently employed by the AAVSO as Membership Director and Development Officer.
His current area of research is Z Cam type dwarf novae, and he is the author or co-author of more than twenty peer-reviewed papers on cataclysmic variables.
In 2005, Simonsen received the AAVSO’s highest honor, the AAVSO Director's Award. In October 2011, Mike became only the third recipient of the Charles Butterworth Award, the British Astronomical Association Variable Star Section’s highest honor. In July 2012, Mike received the Leslie Peltier Award from the Astronomical League. In 2015 the American Astronomical Society named Simonsen recipient of the Chambliss Amateur Achievement Award for his research on Z Cam stars, “which promises to have a long-lasting impact on the field of accretion-disk theory."
Main belt asteroid 367732 is named Mikesimonsen in his honor.
An animated and enthusiastic speaker, Mike gives talks on stellar astronomy and variable star science to astronomy clubs, star parties, planetariums, conferences and university groups throughout the United States each year.
Mike's observatory, named after legendary AAVSO observer and chart maker, Charles E. Scovil, houses two 12" LX200 telescopes, one for visual use and one for CCD observations, or as Mike likes to joke, "One for each eye!" He is now amassing both visual and CCD observations from home and remote robotic telescopes.
He can present one of the talks listed on this website, or create a custom presentation tailored to your audience. Mr. Simonsen is willing to give presentations free of charge within 200 miles of home. If travel will exceed 200 miles, overnight lodging, travel expenses and a meal are the usual requirements.
