Coronal Streamers and Solar Activity
Abstract
We analyze the structure of the streamer belt and plasma ejection dynamics during the last two solar minima (1996-1997 and 2006-2009) using white light observations by SOHO and STEREO space observatories. We consider the role of activity centers and of the sectorial structure of the Sun's global magnetic field in the streamer belt topology. During the last minimum plasma was ejected from the streamer belt at a velocity several tens of km/s higher than that during the preceding minimum. We have used the data from Internet and papers published in science journals.
