Statistical Properties of Solar Proton Events during Solar Cycle 23 and 24
摘要
Abstract
There were totally 128 Solar Proton Events (SPEs) from 1997 to 2016.Their peak flux ranges are from 10pfu to 99pfu,100 to 999pfu,1000 to 2999pfu and greater than 3000pfu,and the percentage is 55.15％,27.94％,9.56％ and 7.35％ respectively.The results show that SPEs with different peak flux have different asymmetry.The SPEs with peak flux ranged from 1000pfu to 2999 pfu have the largest asymmetry,while those with peak flux greater than 3000 pfu have smallest asymmetry.In Solar Cycle 23,the SPEs mainly occurred during the period from the first peak to the second peak and after the second peak of the smoothed monthly mean sunspot numbers.In Solar Cycle 24,the SPEs mainly occurred during the period before maximum of smoothed monthly mean sunspot numbers.关键词
