Solar Activity

Reviews of Geophysics, 1973
The changes in the sun's surface and atmosphere, normally referred to as solar activity, are intimately linked to the production, transport, and dissipation of magnetic fields. The most obvious manifestations of the changes are sunspots, flares, and the changing corona. The complex of solar activity can be divided into two parts: (1) the problem of the

Solar activity

Reviews of Geophysics, 1983
During the past four years, the emphasis in much of the solar research in the United States gradually shifted from the structure of active regions to the nature of the impulsive phase of flares. The first two years of the review interval were dominated by completion of the Skylab data analyses, and especially by the Skylab Workshops on Solar Active ...

Solar radiation and solar activity

Quarterly Journal of the Royal Meteorological Society, 1970
AbstractUsing high‐altitude balloon soundings (1961 to 1968) and other data, it is shown that the most reliable maximum value of the solar constant is at present 1.94 cal cm−2 min−1, to an accuracy of 1 per cent. This value is observed with Wolf numbers between 80 and 100, below or above which the solar constant decreases. The maximum decrease does not
