Tight Loops Close-up
May 20, 2014
We zoomed in almost to our maximum level to watch tight, bright loops and much longer, softer loops shift and sway above an active region, while a darker blob of plasma in their midst was pulled about every which way (May 13-14, 2014). The video clip covers just over a day beginning at 14:19 UT on the 13th. The frames were taken in the 171 Angstroms wavelength of extreme ultraviolet light, but colorized red, instead of its usual bronze tone. This type of dynamic activity continues almost non-stop on the Sun as opposing magnetic forces tangle with each other. Credit: Solar Dynamics Observatory/NASA.
