...transatlantic cable failure and sunspot-caused interference of short wave radio broadcasting dissolved yesterday's proposed debate between members of the Harvard Debate Council and the Cambridge University Debate Union...
About 100 spectators had gathered in Burr B by 4:30 p.m. yesterday afternoon when radio operators expected to establish immediate contact with the Cambridge group. By 5 p.m. however, the Harvard technicians were still unable to reach their Cambridge counterparts over the BBC network because of continuous sunspot interference. Ten minutes later all hope of running the debate was abandoned...
...reasons for choosing 1957-58 as as Geophysical Year was the anticipation of great solar activity--sunspots, flares and "plages" many times the size of the earth--which occurs in roughly eleven year cycles. As long ago as 1946, scientists were looking forward to last year as another peak in the sun-spot cycle; they were amply rewarded, for both 1946-47 and 1957-58 turned in high sunspot peaks. Donald H. Menzel, Director of the Harvard College Observatory, and long a specialist in solar research, agreed that the Sun cooperated beautifully during its intensive examination. In fact...
...Starting in 1927, when transatlantic radiophone service began, the volume of New York-London messages alone had grown from 2,000 to 101,500 in 1955. Meanwhile, wavelength limitations not only overloaded but doomed the transatlantic radiophones to a meager 15 circuits that were at the mercy of static, sunspot interference and fading. Following bursts of sunspot activity, delays on overseas calls sometimes ran up to seven hours; occasionally the blackouts have been known to last for days...
Donald H. Menzel, professor of Astrophysics, who succeeded Harlow Shapley in 1953 as Director of the Observatory, leads the solar and ionosphere work. The Observatory has given up its part in the operation of the High Altitude Observatory at Climax, Colorado, but still shares the newer Sunspot, New Mexico, site of the Air Force's Sacramento Peak Observatory. The instruments include the largest coronagraph in the world, and four super-Schmidt meteor cameras there and at the companion meteor station at Mayhill, New Mexico...
