While physicists are debating the cause of the flares, practical solar meteorologists are learning to identify solar weather conditions that may produce them. First, says Dr. James Van Allen, discoverer of the Van Allen radiation belt, a sunspot must be visible. A group of several sunspots is even more likely to produce a flare, but not all do. Often they fade away without a blowoff...
...riot was the latest flare-up in a seven-week general strike against Ja-gan's high-handed Communist-oriented regime. In April, Jagan introduced a bill in the legislature that would have empowered the government to "supervise" all union elections. Considering the bill a naked attempt to grab control of the country's labor movement, the powerful Trades Union Council called its 50,000 members out on strike. The bauxite mines and sugar mills closed down; so did the docks, railroads and airports. Hardly a store remained open. In the emergency, British technicians arrived to run essential...
...present radio waves are sent over long distances by bouncing them off ionized layers of gas in the earth's atmosphere. Unfortunately, signals from the ionosphere can be jammed, and events such as a large solar flare can cause a radio fadeout by impairing the ionosphere's ability to transmit signals. From a military standpoint, a radio fadeout or jamming could be disastrous in certain situations. Therefore the Air Force supported Morrow's plan, to create a fully reliable global communication system...
...picked last week to announce that two combat-ready battle groups would soon move into Thailand to take part in next month's full-scale SEATO battle maneuvers. It was reminiscent of the crash buildup of troop strength in Thailand just a year ago, when the last serious flare-up in Laos took place. Left behind when these troops were withdrawn were enough trucks, tanks and personnel carriers to equip a third battle group that might be needed in the event of emergency...
...intensity of the ultraviolet radiation that accompanies a solar flare varies from one point of the spectrum to another. Also, at any one wavelength, the intensity varies as the flare moves through the sun's atmosphere. Ultraviolet light is a kind of thermometer, and these changes reflect temperatures varying from about 10,000 to about one million degrees centigrade. As it scans, the Harvard instrument will be recording the occurrence and spread of flares in every region. When the instrument is fixed on the center of the sun, it will provide more detailed information on how and where flares originate...
