Tim methods are not (he same as those used by United States Signal Corps experts, who found that radio impulses sent out to the moon are reflected back 21 seconds later, having made a round trip of 478,000 miles. In the case of the sun, which is 92.900.000 miles away, the signals to be picked up are solar emissions. Sir Edward Appleton, the scientist, states that these are exceptionally intense bursts of radio waves which come from the region around sunspots. “During the coming period of sunspot activity. British research will concentrate on the study of these emissions because of their scientific and practical importance,” he said. Sunspots recur in 11 cycles, and since a cluster of three appeared in 1935 activity will recur this year. During the period of maximum intensity, magnetic storms are produced. Radio emissions produce upheavals in radio and telephone communications.
