Menzel, who had pioneered in constructing H.C.O. solar observation stations in the west, found the facilities in great demand by the IGY Solar Activity Committee. Ordinary observations were increased in number, and special attention was given to a study of cosmic rays, solar flares and radio reception. Involved in the project were three stations built by the Observatory--at Climax, Colorado; Sunspot, New Mexico; and Ft. Davis, Texas. The first station has been turned over to the University of Colorado; the Sacramento Peak Observatory at Sunspot is owned and operated by the H.C.O. under contracts from the Air Force...
...ordinary was happening to the sun came early in the afternoon of the ninth, when an observer, looking through an instrument called a monochromatic heliograph, spotted a flare of breathtaking brilliance leaping out from the Sun's surface. Almost before he could notify the World Data Center on Solar Activity at Boulder, Colorado, confirmation came from the Radio Astronomy Station at Ft. Davis. Bursts of static at 448 megacycles were so loud that the listener called it "Magnitude Major Plus...
Various attempts had been made over the years to correlate magnetic storms with various terrestrial phenomena, and it was to this task that many IGY personnel devoted themselves. A few years ago, a Harvard meteorologist, the late H.H. Clayton, tried to establish a connection between earthly weather and solar activity. It appeared that during peaks of sunspot activity there tended to be more icebergs in northern latitudes, while in the Temperate Zone temperatures were subnormal and precipitation abnormal. It might be pointed out that during the great magnetic storm of February 10 the eastern and central parts of the United...
...most startling new connection between solar activity and terrestrial phenomena was made by men not officially under IGY organization, but working closely with IGY personnel at the Smithsonian. It was typical of a number of important finds; for many of IGY's most distinguished and valuable contributions have come from scientists not working under the Geophysical Year grants from the National Science Foundation. The whole concept of setting aside a year or eighteen months for special cooperation in the sundry fields of science was so broad a project that it touched people whose whole lives have been dedicated to research...
...directly associated with IGY, but working closely with IGY personnel in Cambridge, and a German working in the same field. The discovery--a startling correlation between the movements of five earth satellites and radio wave emission of the sun--is the most marked relation between solar and terrestrial phenomena ever found. The man behind this important find is a good-natured, gray-haired man named Luigi G. Jacchia. A meteor expert by trade, Jacchia may be found more often than not hunched over a drawing board plotting graphs in a small corner office at the Smithsonian Astrophysical Observatory building...
