2 massive ‘active regions’ on the sun have rotated into Earth’s view



Solar activity increased on Jan. 13 as massive active regions of the sun rounded its east limb to face Earth. 

The location of the active regions, designated NOAA 13169 and NOAA 13170, had been predicted previously by the Global Oscillation Network Group (GONG), a network of telescopes across Earth that continuously monitor the sun. The newly visible active regions join other current active regions facing Earth, NOAA 13190, 13191 and 13192, which span the sun’s northern and southern hemispheres.
