Description

Here is now a movie from October 26 covering about 50 hours. Look how this region continues to rotate towards the western limb of the Sun and at the same time also producing solar flares. What's really beautiful is the interaction of all the coronal loops. Coronal loops are found around sunspots and in active regions. These structures are associated with the closed magnetic field lines that connect magnetic regions on the solar surface. Many coronal loops last for days or weeks, but most change quite rapidly.
