IMPORTANCE OF FLARES IN UNDERSTANDING THE ORIGIN OF CMES

摘要

Although the correlation between flares and energetic coronal mass ejections (CMEs) is generally high, there is a trend in which flares are considered to be of secondary importance in the processes of CME initiation. This trend may be aligned with the existence of flares unassociated with CMEs and vice versa. The purpose of this paper is to remind that the term "flare" as it is widely used could confuse the issue, and to propose a new scheme to distinguish different physical processes in flares. Furthermore, we discuss direct low coronal observations of CMEs in their early evolution, including outward motions detected in temperatures 1-10 MK. In order to understand the relation of such motions with CME initiation and coronal/interplanetary shocks, we need to characterize them more unambiguously using multi-wavelength observations.
