AGU's online Space Weather Journal ran a special "news article" highlighting the Boulder science community anniversaries of several key historical events in solar physics and space weather, including HAO's 75th.

Walt Roberts' assignment at the Climax Observatory was to last only one year, but, with the country's sudden entry into the war, he remained at Climax as sole observer, making daily observations of the solar chromosphere and corona.

Seventy-five years ago Walter Orr Roberts helped establish the High Altitude Observatory. A Harvard graduate student, at the time, Roberts and his doctoral adviser, astrophysicist Donald Menzel, founded a small solar observing station high on the Continental Divide in Climax, Colorado. Years later, HAO joined the National Center for Atmospheric Research in Boulder, CO.
