Solar large-scale coronal loops and related active regions

Jie Chen
Swedish Institute of Space Physics

Abstract
Soft X-ray images have revealed that active regions sometimes are connected to each other by coronal loops much larger than active region structures on the Sun. We name this type of coronal loop interconnecting loop (IL). Some large-scale coronal loops are observed to join active regions in the same hemisphere, we call them hemispheric interconnecting loops (HILs); others are observed to connect active regions across the equator which are called transequatorial loops (TLs).
The properties of TL are studied, the formation, evolution of the IL and TL are analyzed. The magnetic properties of the active regions which are related with these loops are introduced.
