The Sun Online and solar activity. November 25, 2013

INFO FROM SIDC – RWC BELGIUM 2013 Nov 25 12:12:38

NOAA AR 1904 was responsible for most flaring activity yesterday, on November 24. Seven C-flares were attributed to this active region which is located in the NE. We expect a similar behaviour: C-flares and the possibility of an isolated M-flare.The solar wind speed is between 300 and 350 km/s. The total interplanetary magnetic field (IMF) is below 5 nT. This results in quiet geomagnetic conditions with the Kp and local K of Dourbes below 4.
The small coronal hole (20 degrees N, front boundary around 20 degrees W, 10 degrees wide) might introduce a geomagnetic disturbance limited in strength and in time from late November 26 onwards.
