[5.07] Disappearing solar filaments and their relation with Coronal Mass Ejections

S. Pojoga, T.S. Huang (Prairie View Solar Observatory)

We investigate the disappearances of solar prominences and filaments and classify them into eruptive, active and quiet events. For this study, we consider a one year period during the most recent maximum of solar activity, from January 1 to December 31, 2000. Prominence and filament disappearances are identified from Prairie View Solar Observatory and Meudon Observatory H-alpha observations as well as from EIT Fe XII 195Åimages. For each type of event we determine the association with the CMEs detected from data obtained by LASCO C2 and C3 coronographs aboard SOHO. Our results indicate that the eruptive events are strongly associated with CMEs while the other types are not. Our data also shows that the results are affected by the size of events and their relative position with respect to the center of the solar disk.
