Transequatorial Interconnecting X-ray Loops and CMEs

Josef I. Khan

Abstract

Evidence is presented which suggests that some coronal mass ejections (CMEs) are preceded by the disappearance of transequatorial interconnecting loops seen in soft X-ray images. These disappearances, which are interpreted as eruptions of the loops, appear to be initiated by coronal shock waves propagating from the flare site at one end of the interconnecting loop structure.  Several examples of such disappearances are presented. The properties and behavior of transequatorial interconnecting loops seen in soft X- rays is examined with regard to their relation to flares and CMEs. The significance of disappearing interconnecting loops in terms of their geo-effectiveness is also discussed.
