The High Altitude Observatory (HAO) is a laboratory of the US National Center for Atmospheric Research (NCAR). HAO operates the Mauna Loa Solar Observatory on Hawaii and a research institute in Boulder, Colorado. Its staff conduct research and provide support and facilities for the solar-terrestrial
physics research community. Topics covered include solar physics, the heliosphere, and the effects of space weather on Earth's magnetosphere, ionosphere, and upper atmosphere. HAO was originally founded in 1940 as a branch of the Harvard College Observatory, was transferred to the University of Colorado in the late 1940s, before becoming part of NCAR when the latter was founded in 1960.
