ON THE 2 CLASSES OF FILAMENT-PROMINENCE DISAPPEARANCE AND THEIR RELATION TO CORONAL MASS EJECTIONS

We analyze the phenomenon of sudden disappearance (DB) of quiescent fi laments and prominences, with examples of the two classes (dynamic and thermal DB) observed on the solar disk and at the limb. The differenc es between their dynamics are discussed, and it is shown that only dyn amic DBs are associated with coronal mass ejections (CME), whereas the rmal DBs are only local disturbances of the lower corona. We finish wi th a discussion of DBs detected on the disk and limb, to explain the s tatistical differences between the disappearance of filaments and the production of CME.
