TO THE QUESTION OF THE LOCALIZATION OF CME GENERATION ON THE SUN

Abstract

The localization of CME occurrence zones on the Sun from November 2006 to February 2007 was studied using the SOHO catalog. A method is described for comparing such zones with active regions (ARs) both in the visible and invisible hemispheres of the Sun. It is shown that a simple linear continuation of the projections of the CME trajectory on the Sun in many cases passes by the AO. 63.5% of CMEs managed to be tied to ARs, 19% failed, and for 17.5% a choice must be made between ARs and flare sites, where spots were observed 1–3 rotations of the Sun earlier. The hypothesis is discussed that the displacement of the beginning of the CME trajectory from the AR centroid is associated with the asymmetry of the location of the magnetic rope, on the basis of which the CME is formed, with respect to the AO: one base of the rope is located near the strong magnetic fields of sunspots, the second is in the region of weak fields on the periphery or outside the AO.
