Magnetic field lines between two active regions extended across about one-third of the Sun to make their connections (July 23-24, 2012). The magnetically powerful active regions were just rotating into view, giving us a wonderful profile of their activity. The lower active region also spurts out several bursts of plasma as well. The looping arcs above each active region shows off the field lines nicely too. The video clip covers about 36 hours of activity in extreme ultraviolet light.
