The Corona www. assignmentpoint. com

Active Region • Caused by strong magnetic fields that may span up to 500, 000 square kilometers www. assignmentpoint. com

Arcade of loops “An "arcade" is a system of magnetic loops organized into an elongated cylindrical formation. Often such an arcade will result from a slowly-developing solar flare or a coronal mass ejection (or both). The bright arcade may persist for days or longer. ” www. assignmentpoint. com

X-Ray Bright Points • These occur anywhere on the Sun at opposition of the active regions. • Caused by magnetic fields that are sucked down into the photosphere www. assignmentpoint. com

Corona Hole • unipolar magnetic fields • high-speed solar wind streams originate in coronal holes www. assignmentpoint. com

Interconnecting loops • large-scale magnetic loops connect two active regions • "emerging flux": magnetic loops push their way through the photosphere and appear in the corona www. assignmentpoint. com
