Sole Active Region in Profile

Oct. 17, 2018
NASA's Solar Dynamics Observatory shows the Sun's rotation bringing a new active region into view, revealing the dynamic arches and twisting streams of its magnetic field (Oct. 10-11, 2018).

The Sun's rotation brought a new active region into view, revealing the dynamic arches and twisting streams of its magnetic field (Oct. 10-11, 2018). A new active region is becoming more of a rare sight, as the Sun is currently approaching solar minimum -- the point of the 11-year solar cycle when activity is most reduced. The video clip, showing images taken in a wavelength of extreme ultraviolet light covers 33 hours and consists of over 500 frames (i.e., one frame selected every 4 minutes).
