The Sun Online and solar activity. December 11, 2013

The Sun is still in a C-flaring mood. It is almost sure that more C-flares will happen. The probability for M-flaring activity is estimated around 40%. There are 9 active regions on the solar disk. Several of them are magnetically connected. NOAA AR 1922 (Catania 74) has grown from nothing to
a beta-gamma configuration.
A partial halo CME was detected on Dec 9, around 21UT. The source region was located in the North-East. We don’t expect this CME to be geoeffective.
A recurrent large coronal hole in the northern hemisphere reached thecentral meridian. It caused previous rotation a Kp of 4. Geomagnetic disturbances are excepted on December 14.
