Sažetak
We studied the relationship between the kinematics of coronal mass ejections (CMEs) and the energy release in the associated flares. For the analysis we have chosen ten events in which the basic CME structure was clearly recognizable already in the low corona during the pre-eruption slow-rise phase. Combining the data gained by the Mauna Loa Solar Observatory, the Large Angle and Spectrometric Corona-graphs and the Extreme Ultraviolet Imaging Telescope on-board the Solar and Heliospheric Observatory, we were able to measure the CME kinematics from the very beginning of the eruption up to the post-acceleration phase. In summary, out of ten cases, five events (50%) showed a relatively good overlap of the CME acceleration phase and the impulsive phase of the flare. Such synchronization indicates that in these events, the CME acceleration and the flare energy release are strongly coupled physical pheno-mena. In three cases there was an obvious mismatch: in two events the CME acceleration took place before the impulsive phase of the flare, and in one event the impulsive phase occurred before the CME acceleration. In two cases (20%) there was no noteworthy soft-X-ray enhancement. Our analysis indicates that in the some events the CME acceleration and the flare energy release are strongly coupled physical phenomena, but in some events the relationship is less prominent.
