Abstract:

Evidence was sought bearing on the understanding of flare mechanisms necessary for a successful system of flare prediction. Intervals between flares in a given region were studied the distribution peaked sharply at 80-100 minutes for simple sunspot configurations, with shorter intervals for more complex groups. The hypothesis was favored that flare energy is supplied into a flaring region at a steady rate, but that the flare occurs when it has built up to an unstable level. Manifestations of flare energy were also studied regarding the question as to whether all of the flare energy discharges during the flash phase of a flare or whether the input continues at a decreasing rate throughout the duration of the flare. Two instances of X-ray curves covering the entire lifetime of flares were found having good Climax rapid-sequence flare hydrogen alpha photographs.
