The Sun Online and solar activity. December 12, 2013

Two long duration C-flares took place today: in the SW (NOAA AR 1912) and in the SE (NOAA AR 1917). Both were associated with a plasma eruption. Yesterday, we had a similar scenario in the SE. A mass of plasma was ejected in the neighbourhood of NOAA AR 1919. Geomagnetic conditions are quiet. A possible influence of a fast stream associated with a coronal hole in the northern hemisphere might arrive on December 14.
