THE INFLUENCE OF RADIO BRIGHTNESS TEMPERATURE ON SOLAR FLARE PREDICTION.
Abstract
An objective technique based on two measured parameters has been developed to determine the probability of occurrence of a solar flare near a sunspot group. The parameters utilized were the size of each sunspot group and the magnitude of an associated radio brightness temperature. Flare, sunspot, and radio data measured daily during the period from April 1962 through October 1966 were used in the study. These data were associated objectively and analyzed statistically. The size of a sunspot group is a significant predictor in itself. This analysis shows that consideration of radio brightness temperature significantly improves the accuracy of solar flare prediction beyond the accuracy that can be achieved by considering only the size of the sunspot group.
