Abstract
Large Doppler velocities with unique, almost regular elliptical features were observed in the Hα spectra of the May 15, 2000 eruptive prominence. These features were interpreted in the frame of axially symmetric models of the eruptive prominence. The rotational (7–60 km s−1), expansion (30–44 km s−1), axial (3–19 km s−1), and global (66–160 km s−1) prominence plasma velocities were derived. The plasma velocity patterns were compared with the observed helical structures of the Hα prominence. The velocities of selected Hα blobs in the image plane were determined. The axially symmetric detwisting process of the magnetic flux rope of the eruptive prominence was recognized.
