Fredericksburg (FRD)

Science Center Objects

The Geomagnetism Program established its first observatory at Cheltenham Maryland in 1900, when the Program was part of the Coast and Geodetic Survey and under the leadership of Drs Louis A. Bauer and John A. Fleming. The observatory was moved to Fredericksburg in 1956, a site which for many years served as the Program’s headquarters. Today, because it has produced high-quality data for so many years, Fredericksburg is one of the world’s most important observatories.
