Photospheric Source Regions of Coronal Mass Ejections
Abstract
Many source regions of coronal mass ejections (CMEs) show signatures of magnetic flux changes prior to the CME onset tep{KM-2005IAUS..226..179M}. In this paper we present a detailed study of the evolution of the photospheric structures using data taken with MDI onboard SOHO. Magnetograms and Dopplergrams are used to characterize the flux changes that happen in connection with the CMEs. We discuss the implications of our findings on the initiation of CMEs.
