"Observing Variable Stars, and the AAVSO"

Terry Benner


Terry Benner has been an amateur astronomer since the very early seventies.  Over the past 45+ years his interests have encompassed nearly all aspects of amateur astronomy.  Terry was a member of IOTA (International Occultation Timing Association) and joined the AAVSO (American Association of Variable Star Observers) in 1980.  Since then, Terry has reported 17,588 visual magnitude estimates to the AAVSO, focusing mainly on cataclysmic variables, old novae and R Coronae Borealis stars while still reporting on a numerous array of Long Period Variables.

THE LEHIGH VALLEY AMATEUR ASTRONOMICAL SOCIETY -- 620B East Rock Road -- Allentown, PA 18103 -- 610-797-3476 --


Founded in 1957, the Lehigh Valley Amateur Astronomical Society (LVAAS) is one of the oldest continuously-operating amateur astronomy organizations in the U.S. The mission of LVAAS is to promote the study of Astronomy and to maintain a meeting space, observatories, and a planetarium.

LVAAS operates two astronomy sites: The South Mountain site in Salisbury Township is the headquarters of the Society. It has a planetarium with a Spitz A3P projector, a 21 foot dome, meeting space, the Red Shift store, library, workshop space, and three observatories. The Pulpit Rock site near Hamburg is LVAAS's members-only dark sky site. At 1600 feet above sea level, the site features five observatories and a pad for member's scopes.

Members who receive training on the scopes may obtain keys to the observatories. LVAAS also maintains a rental "fleet" of telescopes that members may rent at low cost. Members also receive access to The Observer, our online newsletter, as well as reduced subscription prices to Sky and Telescope and Astronomy Magazine. If you want to learn more about astronomy and LVAAS, please join us at our next public star party.
