The birthplace of planetary radio astronomy: The Seneca, Maryland observatory 50 years after Burke and Franklin's Jupiter radio emission discovery.

Burke and Franklin’s discovery of radio emissions from Jupiter in 1955 effectively marked the birth of planetary radio astronomy. The discovery was made near Seneca, Maryland using the Department of Terrestrial Magnetism/Carnegie Institution of Washington’s (DTM/CIW)Mills Cross Array. Fifty years later no evidence of this 96-acre X-shaped array of dipoles remains. The site, now known as the McKeeBeshers Wildlife Management Area, is owned by the State of Maryland Department of Natural Resources. This workshop and Radio Jove (http://radiojove.gsfc. nasa.gov), a NASA/GSFC education and public outreach project, have put special emphasis on making this event known to the scientific community and the general public. We describe some results of our search through the DTM/CIW archives, our success at having the state of Maryland officially recognize this historic site, our own visit to the site to look for evidence of the array, and other efforts at commemorating this anniversary.
