摘要 | The present paper is concerned with a preliminary statistical analysis of the photographical morphology of sunspot groups observed at Yunnan Observatory during March 1970– December 1972. 1. 1. There exists a higher frequency (⩾55%) of flare production in those regions in which persistent (⩾2 days) penumbral spiral structure is observed. 2. 2. There is a close correlation (∼ 84%) between the above mentioned regions and energetic flares. 3. 3. About 90% of energetic flares in the above mentioned regions appeared an average of 3.8 days later after the occurrence of spiral spots. A possible cause and ef effect relation may exist in these phenomena. The above conclusions may be useful in the construction of a flare theory with reference to twisting instability of magnetic field. |
