标题： Space Storm Measurements of 17 and 21 April 2002 Forbush Effects from Artemis-IV Solar Radio-Spectrograph, Athens Neutron Monitor Station and Coronas-F Satellite

摘要： 在本报告中，我们介绍了两个复杂的爆发性太阳事件及其相关的宇宙射线效应（Forbush减少）。 我们使用了来自多个地球接收器、空间实验和数据档案的联合记录（如ARTEMIS-IV射电光谱仪、雅典中子监测器、LASCO CME列表、{CORONAS-F}卫星的SONG等）。 分析和讨论了太阳瞬变对星际介质条件和宇宙射线通量的影响。 这一时期观测到的事件时间序列表明，CME的启动与II型和IV型射电爆发以及强烈的太阳耀斑的出现密切相关。 它们的影响从低日冕延伸到近地空间，影响宇宙射线测量和空间天气。 关于Forbush减少，我们的数据显示在存在MHD激波时有显著增强。 显示英文摘要

摘要： In this report we present two complex eruptive solar events and the associated Cosmic Ray effects (Forbush decrease). We use combined recordings from a number of Earthbound Receivers, Space Experiments and data archives (such as the ARTEMIS-IV Radio spectrograph, the Athens NEUTRON MONITOR, the LASCO CME Lists, the SONG of the {CORONAS-F} satellite, etc.). The influence of solar transients on the interplanetary medium conditions and the cosmic ray flux is analysed and discussed. The observed time sequence of events of this time period indicates that the initiation of CMEs is closely related to the appearance of type II and IV radio bursts and strong solar flares. Their effects extend from the lower corona to the near Earth vicinity affecting Cosmic Ray measurements and space weather. As regards the Forbush decrease our data indicate significant amplification at the presence of a MHD shock.
