RECORDED IN 1943
EMISSIONS FROM SUN U.S. RADAR SCIENTISTS HISSING NOISE MEASURED (10 a.m.) NEW YORK, Jan. 30. The Australian radio physicists' feat of recording noise waves from the sun was performed in New York in 1943 by engineers of the Eell Telephone Company’s laboratories. Colonel J. H. Dewitt, who supervised the American Army’s radar contact with the moon, termed the Australian news “pretty old,” and said: “We have been able to trace the sun with radar for some time. The sun has such a high temperature that it radiates thermal noises which we can pick up at certain wave lengths.” The Bell Telephone Company’s engineers used a double-detection superhetrodyne receiver, modified to operate on extremely short wave lengths, and measured hissing noises emanating from the sun. The scientists said the rays from the moon and from Veta, one of the brightest stars, were broadcast in 1934 from Bratislava and Prague to Britain. The rays made sounds similar to the tolling of large bells.
