After World War II, says Gartlein, the sunspot cycle turned upward, reaching its peak in the winter of 1948-49. That was a time of troubles in the electrical world, when the sunspots' pesky particles disrupted communications for entire days. Then the cycle turned downward again. In the fall of 1950, the sun showed an almost spotless face for the first time in six years. The bottom of the cycle will be reached in 1954. So, says Dr. Gartlein, the U.S. and its friends (who are more electrical-minded than the Reds) will have the sun's help...
...unusually large sunspot which has been reappearing persistently over the last few months has caused less interference with radio and wire communications than expected, Donald H. Menzel, professor of Astrophysics, said last night...
Richard B. Duun 1G, teaching assistant in Astronomy, noted that the spots, especially the one measuring over 100,000 miles in diameter, are unusual for this period in the sunspot cycle...
...Sunspot frequency hits a maximum every 11 years. The cycle is now approaching its minimum, which makes the present outbreak of sunspots unusual...
...many years astronomers have been pretty certain that the Aurora Borealis is caused by something, presumably hydrogen, that is shot out of sunspots. For one thing, bright auroras generally appear about 15 hours after a sunspot has moved to a point on the sun directly opposite the earth. But proof was lacking; even the brightest auroras were too faint and diffuse to be studied spectrographically by existing instruments. Last week the proof was in hand: a few smudged bands on two photographic plates...
