Well not really clouds, all the same, this is something to see.

Better yet check out the “best” version of the movie mentioned in the caption (below) from the SDO site (click to see other movie formats).

A dark clump of plasma rose up above the Sun, then twisted and spun about before it broke away and dissipated (Dec. 16-17, 2013). You can see the effect of magnetic forces pulling it this way and that over the 12-hour video clip before it is thrust into space by a coronal mass ejection. The large, bright loops emerging from the Sun north of the small mass trace magnetic field lines above several active regions. The images were taken in a wavelength of extreme ultraviolet light that reveals ionized iron heated to a million degrees.
