摘要

本文的重点是识别和研究2023年前几个月的几次大规模太阳风扰动和相关的Forbush效应。利用全球中子监测网的数据，采用全球测量法获得了宇宙射线通量（刚性为10 GV）的变化。2023年初的特点是福布什效应相对较多；最大的地震发生在2月26日至28日、3月15日至16日、3月23日至25日和4月23日至24日。详细讨论了这些事件及其与太阳风参数、地磁活动和相关太阳源的关系。从行星际扰动的数量和强度以及相应的宇宙射线变化来看，2023年2月至4月被证明是第25太阳周期开始以来的第一个活动期。

On the Most Interesting Solar-Wind and Cosmic-Ray Events in February–April 2023

The article focuses on identifying and studying several large-scale solar-wind disturbances and associated Forbush effects in the first months of 2023. Variations of the cosmic-ray flux (with 10 GV rigidity) are obtained using the Global Survey Method with data from the global network of neutron monitors. The beginning of 2023 is characterized by a relatively large number of Forbush effects; the largest ones were recorded on 26 – 28 February, 15 – 16 March, 23 – 25 March, and 23 – 24 April. These events and their relationship with solar-wind parameters, geomagnetic activity, and associated solar sources are discussed in detail. In terms of the number and magnitude of interplanetary disturbances and corresponding cosmic-ray variations, February–April 2023 proves to be the first active period since the beginning of Solar Cycle 25.

期刊介绍： Solar Physics was founded in 1967 and is the principal journal for the publication of the results of fundamental research on the Sun. The journal treats all aspects of solar physics, ranging from the internal structure of the Sun and its evolution to the outer corona and solar wind in interplanetary space. Papers on solar-terrestrial physics and on stellar research are also published when their results have a direct bearing on our understanding of the Sun.
