DEVELOPING A SYSTEM OF SOLAR FLARE PREDICTION
Abstract
Work was directed toward study of the intervals between flares in the same region. The objective of the study is to find evidence whether flares occur as the explosive discharge of energy that has been built up gradually, or whether they occur when statistical fluctuations in the magnetic field configurations lead to an instability. It was found, in the case of flares over simple sunspot configurations, that the frequency histogram for various intervals between flares peaks rather sharply at 80-100 minutes, whereas for more complex spot groups the peak broadens toward shorter intervals. The results were interpreted as favoring the hypothesis of build-up and discharge. The time interval gives evidence of the rate of energy-input during the build-up period and also provides a basis for predicting the frequency of flares from an active region.
