In the Loops
A pair of solar active regions spun up dozens of arching loops above them and extending an estimated 100,000 miles between them as they rotated into view over the period of one day (Mar. 26-27, 2013). Active regions are areas of intense magnetic forces pushing up from beneath the solar surface. The loops are charged particles spinning along the magnetic field lines as observed in extreme ultraviolet light. Active regions are often the sources of solar storms, so we will be keeping our eye on them.
