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 Coronal Mass Ejection (CME) and the energy release in the associated flare. The basic structure of the CME (prominence imbedded in bright coronal arcade) is clearly recognizable already in the low corona during the pre-eruption phase of slow rise. This provided measurements of kinematics of various 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 occasionally, 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 1.45 solar radii from the Sun's center and ceased beyond 4 solar radii. The acceleration phase was synchronized with the impulsive phase of the associated two-ribbon flare. Observations provide clear evidence that the CME eruption caused a global restructuring of the magnetic field in the outer and inner corona.
