We study variations in the rigidity spectrum and anisotropy of cosmic rays (CRs) by using the data from satellite and ground-based observations within the worldwide network of cosmic-ray detectors through the global spectrographic survey. The studied period covers 28 and 29 October and 2 November 2003 (GLE65, GLE66, and GLE67). We determined CR differential rigidity spectra at individual hours of the investigated events. The maximal rigidity of accelerated protons in these GLEs is shown to equal ~ 4–14 GV.

2003 年 10 月至 11 月宇宙射线的地面增强

我们通过全球光谱调查，利用全球宇宙射线探测器网络内的卫星和地面观测数据，研究宇宙射线 (CR) 的刚度谱和各向异性的变化。研究期间涵盖 2003 年 10 月 28 日至 29 日和 11 月 2 日（GLE65、GLE66 和 GLE67）。我们在调查事件的各个小时确定了 CR 差异刚度谱。这些 GLE 中加速质子的最大刚度显示为约 4-14 GV。
