Ukiah Observatory
The International Latitude Observatories were a system of (originally) six observatories located near the parallel of 39° 082 north latitude. They were used to measure the variation in latitude that occurs as a result of the wobble of the Earth on its axis.
United States Coast and Geodetic Survey (today the NGS) joined the International Polar Motion Service program in 1897 to study the precession, or wobble of the Earths axis, and its effect on measures of latitude. Six separate observatories were created along the parallel 39° 082 north latitude. The alignment of all six stations along the parallel helped the observatories to perform uniform data analysis.
The data collected by the Ukiah observatory are very much still relevant. The foundation for the studies of polar motion, the physical properties of the Earth, climatology and satellite tracking and navigation, are just a few of the modern day results of the incredible science that has fundamental root ties to these Observatories.
Heritage Asset on Loan to City of Ukiah, CA
NGS recently loaned the City of Ukiah, California, a Wanschaff zenith telescope for display in the original observatory building where it was used for nearly a century. This zenith telescope was one of six used to observe the wobble of the Earth on its axis. The International Geodetic Association organized a formalized polar motion program in 1899, with a central bureau in Europe and six observing stations, each situated near latitude 39° 08' north, with observatories in the United States located in Ukiah, California, and Gaithersburg, Maryland. NGS transferred ownership of the Ukiah observatory to the city at the end of the program, and the property is now a city park.
Initially carried out by astronomers, this program was actually a study in geodesy and Earth physics. The loan will help promote NGS and Ukiahs rich historical heritage.
