Background

The Boulder observatory was established in 1961. The grounds for the observatory are overseen by the National Telecommunications and Information Administration of the Department of Commerce. The Boulder observatory is that which is located closest to Program headquarters in Golden. Therefore, in addition to serving as a site for routine data collection, Boulder also functions as the Program’s test bed for on-going operational developments. Several new buildings have recently been installed on the site and Program staff are currently working to install a coil-calibration facility.
