Abstract

Abstract: 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. Highlights: Kinematic study of solar eruptive prominences. Detected periodic changes of the velocity distribution of the plasma in height during prominence eruption. Possible over-passing of magnetic loops by the prominence materialbelow the critical height of about 400 000 km.
