Since its founding in 1911, the American Association of Variable Star Observers (AAVSO) has coordinated, collected, evaluated, analyzed, published, and archived variable star observations made largely by amateur astronomers and makes the records available to professional astronomers, researchers, and educators. These records establish light curves depicting the variation in brightness of a star over time.
The Astronomical Society of the Pacific (ASP) is an American scientific and educational organization, founded in San Francisco on February 7, 1889. Its name derives from its origins on the Pacific Coast, but today it has members all over the country and the world. It has the legal status of a nonprofit organization.
The Center for Astrophysics | Harvard & Smithsonian (CfA) is an astrophysics research institute jointly operated by the Harvard College Observatory and Smithsonian Astrophysical Observatory. Founded in 1973 and headquartered in Cambridge, Massachusetts, the CfA leads a broad program of research in astronomy, astrophysics, Earth and space sciences, as well as science education. The CfA either leads or participates in the development and operations of more than fifteen ground- and space-based astronomical research observatories across the electromagnetic spectrum, including the forthcoming Giant Magellan Telescope (GMT) and the Chandra X-ray Observatory, one of NASA's Great Observatories.
Leon Mestel was a British-Australian astronomer and astrophysicist and Emeritus Professor at the University of Sussex. His research interests were in the areas of star formation and structure, especially stellar magnetism and astrophysical magnetohydrodynamics. He was awarded both the Eddington Medal (1993) and the Gold Medal of the Royal Astronomical Society. Following his retirement, he wrote several obituaries and biographical articles on physicists and astrophysicists.
Dinsmore Alter was an American astronomer, meteorologist, and United States Army officer. He is known for his work with the Griffith Observatory and his creation of a lunar atlas.

Goodsell Observatory is an observatory at Carleton College in Northfield, Minnesota, United States. It was constructed in 1887 and was, at the time, the largest observatory in the state of Minnesota. The Goodsell Observatory and its predecessor, a smaller observatory that opened in 1878, served as a widely consulted timekeeping station, bringing national prominence to Carleton College in the late 19th and early 20th centuries.
Sarah Lee Lippincott, also known as Sarah Lee Lippincott Zimmerman, was an American astronomer. She was professor emerita of astronomy at Swarthmore College and director emerita of the college's Sproul Observatory. She was a pioneer in the use of astrometry to determine the character of binary stars and search for extrasolar planets.
The Georgetown University Astronomical Observatory was founded in 1841 by Father James Curley of the Department of Physics at Georgetown College. Father Curley chose a site on the college grounds, planned the building, and supervised its construction to its completion in 1844. Costs were initially paid by Rev. Thomas Meredith Jenkins, S.J., and Rev. Charles H. Stonestreet, S.J., who were Georgetown professors at the time. The observatory was used in 1846 to determine the latitude and longitude of Washington, D.C., which Curley determined to be latitude 38°54′26N and longitude 5h8m18.29s.
Susan Jane Cunningham was an American mathematician instrumental in the founding and development of Swarthmore College. She was born in Maryland, and studied mathematics and astronomy with Maria Mitchell at Vassar College as a special student during 1866–67. She also studied those subjects during several summers at Harvard University, Princeton University, Newnham College, Cambridge, the Royal Observatory, Greenwich, and Williams College.
The Daniel S.
