论文摘要
对太阳能颗粒事件(SEP)的研究及其与太阳耀斑和其他活动的关联对于了解太空天气至关重要。考虑到这一点,在本文中,我们介绍了在太阳周期21至24(1976-2017)中的SEP(强度等于或大于10 PFU)的研究,> 10 MeV能量通道与太阳能耀斑相关。为了进行分析,我们使用了来自SOHO卫星的不同工具的数据。我们已经检查了相关SEP的耀斑尺寸,源位置,CMES特征。大约31%和69%的SEP分别起源于东太阳半球和西部半球。平均CME速度和宽度分别为1238 km/s和253度。大约58%的SEP与Halo CME相关,与CMES宽度相关的SEP中有42%分别从10度到250度不等。
The study of the solar energetic particle events (SEPs) and their association with solar flares and other activities are very crucial to understand the space weather. Keeping this in view, in this paper, we present the study of the SEPs (intensity equal to or greater than 10 pfu) during the solar cycle 21 to 24 (1976-2017) in > 10 MeV energy channels associated with solar flares. For our analysis, we have used the data from different instruments onboard SOHO satellite. We have examined the flare size, source location, CMEs characteristics of associated SEPs. About 31% and 69% of the SEPs were originated from the eastern and western solar hemisphere respectively. The average CME speed and width were 1238 km/s and 253 deg respectively. About 58 % SEPs were associated with halo CMEs and 42% of SEPs associated with CMEs width varying from 10 deg to 250 deg respectively.
