[i]These six images from SDO, chosen to show a representative image about every six months, track the rising level of solar activity since the mission first began to produce consistent images in May, 2010. The period of solar maximum is expected in 2013. The images were taken in the 171 Angstrom wavelength of extreme ultraviolet light.

[i]This minor eruption rises and falls with the grace and polished movement of a ballet dancer (Oct. 4, 2012). The close-up video at just about full resolution captures the event in extreme ultraviolet light with this 2.5-hour observation. Most of the particles do not have enough momentum to break away into space and are pulled down again into the Sun. The movie was made using an image every 15 seconds, played back at 15 frames per second.

[i]This segment (Sept. 29 - Oct. 2, 2012) shows multiple connections between active regions as viewed in extreme ultraviolet light. Some of the brighter loops arc up and back to the same region and we see that here as well. However, many of those coronal loops extend their tenuous reach to other active regions quite clearly, with some of the field lines stretching at least 200,000 miles. The active regions are magnetic in nature, often leading to these multiple interconnections.
