Abstract—

The first (preliminary) results of a systematic search for minor ground level enhancement (GLEs) in solar cosmic rays (SCRs) in the 24th solar activity cycle are presented. The search was conducted based on the data of the global network of neutron monitors with allowance for the results of direct satellite measurements. The initial assumption is that such increases point to the possible acceleration of solar particles in shock waves, which are generated by coronal mass ejections. The shape of the integral spectrum of the accelerated particles according to observations of neutron monitors and measurements from near-Earth space vehicles could serve as a determinant for checking that hypothesis. Studying the spectra manifests an informativity of our approach to a better understanding of SCR source properties.

第24个太阳活动周期中太阳宇宙射线的次要地平面增强

摘要-

给出了系统搜索第24个太阳活动周期中太阳宇宙射线（SCR）的次要地平面增强（GLE）的第一个（初步）结果。搜索是基于中子监测器全球网络的数据进行的，并考虑了直接卫星测量的结果。最初的假设是，这种增加表明了由日冕物质抛射产生的冲击波中太阳粒子的可能加速。根据中子监测器的观测和近地航天器的测量，加速粒子的积分光谱形状可以作为检验该假设的决定因素。研究光谱表明，我们的方法具有信息性，可以更好地理解SCR离子源的特性。
