Abstract

The results of studying the fluxes of solar protons with energies greater than 5 MeV in near-Earth space on March 13–23, 2023, are presented. The features of the period under study are no visible solar flare with which the beginning of the event could be associated and an untypical time profile of proton fluxes, as well as a long duration of the existence of solar proton fluxes in near-Earth space. An attempt was made to explain the sources of the observed different variations in particle fluxes and to understand what happened on the Sun and in the near-Earth space. The source of solar protons on March 13, 2023, was an explosive process on the back side of the Sun from the Earth, registered as a coronal mass ejection of very high power. The reason for the long and complex time profile of solar protons was the contribution of particle acceleration processes on the Sun and in the interplanetary medium, as well as the modulation of particle fluxes by the structures of the interplanetary magnetic field. A possible scenario has been proposed to explain the existence of increased fluxes of solar particles on March 15–23, 2023: the formation of a heliospheric structure, this being a closed trap region formed by two interplanetary coronal mass ejections and regions of interaction of high-speed and slow solar wind streams. The study uses experimental data obtained from the Solar Orbiter spacecraft and from spacecraft located near the L1 point of the Earth–Sun system (ACE and DSCOVR) and in geostationary orbit (GOES-16).

2023 年 3 月 13-23 日近地空间的太阳能量质子通量

摘要介绍了对 2023 年 3 月 13 日至 23 日近地空间能量大于 5 MeV 的太阳质子通量的研究结果。研究期间的特点是没有明显的太阳耀斑（事件的开始可能与此有关）和质子通量的非典型时间曲线，以及太阳质子通量在近地空间存在的持续时间较长。我们试图解释所观测到的粒子通量不同变化的来源，并了解在太阳和近地空间发生了什么。2023 年 3 月 13 日太阳质子的来源是来自地球的太阳背面的爆炸过程，表现为一次高功率的日冕物质抛射。太阳质子的时间曲线漫长而复杂，其原因是太阳和行星际介质中的粒子加速过程，以及行星际磁场结构对粒子通量的调节。为了解释 2023 年 3 月 15 日至 23 日太阳粒子通量增加的现象，提出了一种可能的情况：日光层结构的形成，即由两次行星际日冕物质抛射以及高速和慢速太阳风流相互作用区域形成的封闭陷阱区域。这项研究使用了太阳轨道器航天器和位于地日系统 L1 点附近（ACE 和 DSCOVR）及地球静止轨道（GOES-16）上的航天器获得的实验数据。
