Three case studies of height-time profiles of prominence eruptions observed by AIA and LASCO

The motions of three solar eruptive prominences are studied. The behaviour of the rising prominence body during the eruption is tracked. Height-time profiles of the eruption up to 6 R⊙ (based on observations by Solar Dynamics Observatory/Atmospheric Imaging Assembly (HeII 304 Å) and Large Angle and Spectrometric Coronagraph Experiment (LASCO) C2/Solar and Heliospheric Observatory (SOHO)) and possible changes of the velocity of the prominence material are presented. The mechanisms that generate the variations in the material movement are discussed.
