Scientific paper

Observations of an eruptive and a quiescent prominence are compared in order to understand better the energetic processes in an eruptive prominence. Several differences are pointed out which suggest that the activation consists not only of a mechanical movement of material, but also changes in the temperature of the prominence plasma. Some prominence material that does not seem to participate in the large-scale prominence motion is heated during the eruptive event. Most of this material is heated to transition zone temperatures with almost no cool 'core'. The behavior indicates that there are structures that are first cool and then heat up to transition zone temperatures, apparently remaining stable for some time at these temperatures.
