摘要：

We study the relations between coronal streamers obtained from the LASCO 2 coronograph of SOHO and the condition of solar activity in the photosphere and chromosphere in the of minimum period of the last cycle of solar activity. From data obtained on SOHO (coronal streamers, Fe XV, He II) we selected two intervals, each about twenty days. For every day a flare index and sunspot activity was calculated and these data were confront with SOHO pictures of Sun. The evolution of helmet streamers in connection with the others parameters mentioned was studied. Relationships of evolution of helmet streamers with fluxes of high speeds electrons (more than 2MeV) obtained by GOES 7 was also studied.
