A series of linked loops across the face of the Sun highlighted the dynamic magnetic connections generated by several active regions (Jan. 3-6, 2015). Active regions have magnetic north and south polarity and the arcing loops find the opposite pole to make the connection. What is unusual here is that they all kind of line up and link nicely together. These movies are made in a wavelength of extreme ultraviolet light. Credit: Solar Dynamics Observatory, NASA.
