Coronal Mass Ejection of 28 June 2000: Coupling of the CME Evolution and the Flare Energy Release

We study the initiation and development of the limb coronal mass ejection (CME) of 28 Jun 2000, utilizing observations from Mauna Loa Solar Observatory (MLSO), the Solar and Heliospheric Observatory (SOHO), the Geostationary Operational Environmental Satellite (GOES) and Yohkoh. Also, we analyze the relation between dynamics of the CME and the energy release in the associated flare. A complicate stucture (prominence and bright overlying arcades) is clearly recognizable in the low corona during the pre-eruption phase of slow rise. This provided measurements of kinematics of verious features from the very beginning of the eruption up to the post-acceleration phase which was followed up to 32 solar radii. Such events are observed only occasionaly, and are of great importance for the comprehension of the nature of forces driving CMEs. The acceleration maximum was attained at the radial distance of 1, 3RSun from the Sun's center and ceased beyond 4 solar radii. Observations provide clear evidence that CME eruption is causing a global restructuration of the magnetic field in the outer and inner corona. Furthermore, kinematics and morphological properties of this CMEs show possibility that various features of CME have diferent driver.
