The Sun Online and solar activity. November 13, 2013

The flaring activity during last 24 hours was on the C-class level. The strongest flare observed was the C 9.8 flare (peaked at 23:08 UT on November 12) originating from the NOAA AR 1897. We expect flaring of the C-class and also M-class level, X-class flares are possible but not very probable. Flaring is expected in particular from the Catania sunspot group 35 (NOAA AR 1890) and NOAA AR 1897. Due to the position of Catania sunspot group 35 (NOAA AR 1890) we maintain the warning condition for a proton event. The CME first observed in SOHO/LASCO C2 field of view at about 07:00 UT on November 12, will not arrive at the Earth. The Earth is currently inside a slow solar wind flow with the speed of about 400 km/s. The interplanetary magnetic field is stable with the magnitude of 4 nT.  The arrival of the fast solar wind stream from a low-latitude coronal hole in the northern hemisphere which reached the central meridian today, is expected late on November 16. The geomagnetic conditions are currently quiet. We expect active geomagnetic conditions in the following hours due to arrival of the halo CME which erupted on November 10.
