Detailed description is 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 longitude 38°54′26N and latitude 5h8m18.29s.In 1850, Benedict Sestini used the observatory to make a series of sunspot drawings, which were engraved and published as "Appendix A" of the Naval Observatory volume for 1847, printed in 1853. In 1888, Johann Georg Hagen was named director. He was responsible for the installation of the 12-inch equatorial telescope with which for twenty years he observed and gathered data on variable stars. This instrument is still in continuous use. In 1928, Paul McNally became director. Francis J. Heyden, S.J. became director in 1945, and continued research into solar eclipses. In 1972, Georgetown University closed its Department of Astronomy, and the observatory was used by the Georgetown University Astronomical Society. Light pollution from surrounding Washington, D.C. has limited viewing celestial bodies from the location.
