论文摘要
除了最近几篇专门针对10月28日（GLE73）观察到的太阳相对论质子通量的罕见事件（GLE73）的罕见事件外，我们还研究了此事件的10-100 MEV太阳能粒子（SEP）成分。基于自1986年以来记录的26个GLE的GOO卫星数据，我们形成了一个散点图，显示了> 10 MeV（J10）和> 100 MeV（J100）质子及其能量光谱的峰值磁通量的比率。揭示了Sep-Gle73事件的迅速成分的两个极端特征：（1）非常小的J10和J100质子通量，以及（2）在10-100 MEV范围内非常坚硬的能量频谱。这些特征只有两个类似于Sep-Gle73的事件，即Gle40（1989年7月25日）和GLE46（1989年11月15日）。在启动耀斑的微波无线电爆发的硬频谱与这两个和其他Gles的硬性SEP能量光谱之间证明了对应关系。这些结果表明，冲动性和爆发后的耀斑磁重新连接在SEP-GLE质子的加速度中起着重要作用。
In addition to several recent articles devoted to the rare event of ground-level enhancement of the solar relativistic proton flux observed on 2021 October 28 (GLE73), we study the 10-100 MeV solar energetic particle (SEP) component of this event. Based on the GOES satellite data for 26 GLEs recorded since 1986, we have formed a scatter plot displaying the ratio of the peak fluxes of the >10 MeV (J10) and >100 MeV (J100) protons and their energy spectra. Two extreme characteristics of the prompt component of the SEP-GLE73 event were revealed: (1) very small J10 and J100 proton fluxes and (2) a very hard energetic spectrum in the 10-100 MeV range. There are only two events with these characteristics similar to SEP-GLE73 namely, GLE40 (1989 July 25) and GLE46 (1989 November 15). A correspondence was demonstrated between the hard frequency spectrum of microwave radio bursts of initiating flares and the hard SEP energy spectrum of these two and other GLEs. These results suggest that the flare magnetic reconnection both in the impulsive and post-eruption phases plays an important role in the acceleration of the SEP-GLE protons.
