Magnetic Coiling

July 18, 2016
One broad active region sported a wonderful example of coiled magnetic field lines over almost a four-day period observed by NASA's Solar Dynamics Observatory during July 15-18, 2016.

One broad active region sported a wonderful example of coiled magnetic field lines over almost a four-day period (July 15-18, 2016). The magnetic lines are easily visible in this 171 Angstrom wavelength of extreme ultraviolet light be cause charged particles are spiraling along the lines. The active region is a hotbed of struggling magnetic forces that were pushing out above the sun's surface.
