摘要

本文提供了第21太阳活动周期观测到的太阳活动复合体的统计资料。从1976-1986年的太阳黑子活动天气图中,我们至少通过三次卡林顿旋转(Carrington rotation, cr)发现了观测到太阳黑子产生的区域。这些区域被确定为交流核心。我们编制了一份AC目录。ac显示出准周期性的进化,在15-20个旋转长的脉冲中。我们分析了交流位置的南北不对称性。在第21周期中,90%的影响自然环境的质子耀斑发生在ac中。我们注意到,在太阳活动周期21-24中,交流电活动有减少的趋势,并且在交流电性质中表现出格内维舍夫-欧尔规则。

Complexes of activity on the Sun in solar cycle 21
The paper provides statistical data on solar activity complexes (ACs) observed in solar cycle 21. From the synoptic charts for the 1976–1986 sunspot activity, we have detected the regions where the sunspot generation was observed at least through three Carrington Rotations (CRs). These regions were identified as AC cores. We have compiled an AC catalogue. ACs are shown to evolve quasi-periodically, in pulses that are 15–20 rotations long. We have analyzed the North-South asymmetry in the AC location. In cycle 21, 90 % of the proton flares that affected the natural environment are shown to have occurred in ACs. We note a tendency for AC activity to decrease, as well as the manifestation of the Gnevyshev—Ohl rule in AC properties, in solar cycles 21–24.
