m iiiiDi] JOHN H. NELSON, RCA RADIOWAVE ANALYST, TRAINS HIS TELESCOPE ON THE SUN FROM HIS ROOFTOP OBSERVATORY AT 25 BEAVER STREET, NEW YORK CITY, WHERE HE DISCOVERED EVIDENCE OF A NEW RELATION- SHIP BETWEEN THE POSITIONS OF PLANETS AND MAGNETIC STORMS. WHEN PLANETS AND SUN ARE IN THE POSITIONS SHOWN IN THIS DIAGRAM, THE RESULTING BOMBARDMENT OF THE EARTH BY MAG- NETIC STORMS REACHES ITS MAXIMUM INTENSITY. — 350' 340* 320" ^ ances occur more frequently c the earth's surface.

By means of his planetary r search, Mr. Nelson has been at to predict for two years in advan the approach of major magnet disturbances on the earth's surfac Combining his planetary observ tions with a daily telescopic i spection of the sun's surface, he h obtained an accuracy of 85 per ce in his daily forecasts of good ai bad radio weather.

Planets Affect Solar Surface Although Mr. Nelson's reseai was related to the earth's magne storms in relation to radio co munications rather than sunspc his study indicates that the plan- inrtuence the surface of the s and the solar reactions frequen associated with sunspots. In developing evidence of plai tary influence, Mr. Nelson prepai hundreds of charts of planet pc tions, radiotelegraph circuit havior and sunspots, and then cc pared the relationships betwi them.
