Hα-SSHG Observation and Research of the Flare Loop of May 21, 1984

摘要: 利用云南天文台太阳光谱分光照相仪(Hα-SSHG),拍摄了1984年5月21日边缘耀斑环珥的Hα光谱资料,结合Hα色球观测资料给出了该事件的发展过程和色球、光谱的形态特征。定性地探讨了该耀斑环内的宏观物质运动.用提出的双环系模型能较好地解释观测结果.Abstract: The Ha spectroheliograms of the limb flare loop prominence which erupted on 1984 May 21 have been taken with the Ha spectro-spectraheliograph (Hα-SSHG) of the Yunnan Observatory of the Chinese A cademy of Sciences. By combining them with the Hα chromospheric observations, the process of development and the chromospheric and spectral morphological features of the event are given in this present article. A qualitative approach to the macroscopic motion of matter of the flare loop is carried out. The observations can be well explained by means of a proposed two-loop system model.
