ocr: CORONA According to some of the newest observations, the larger and higher magnetic loops are believed to hold down the newer and smaller fields emerging from the surface. They also tie down the hot plasma carried by those fields. This causes tremendous energy tol build. Eventually, some of the overlying magnetic loops merge and cancel each other, cutting a hole in the magnetic net and allowing the coronal mass ejection (CME) to escape at high speed. The corona extends outward as solar wind. Coronal holes are gaps in the corono, regions of reduced emission, reduced density, and increased speed ...
