Visible side of the solar disc is spotless. There were no flares reported for number of days and we do not expect any flaring activity in the coming hours. Narrow and slow, but well defined CME reported yesterday (observed in the SOHO LASCO C2 field of view at about 19:06 UT on December 09) was associated with the brightening and small dimming at about 18:11 UT (situate at S05 W25). It is not probable that this CME will arrive to the Earth. During last 24 hours there were no Earth directed CMEs and the solar protons remained at the background level.

The solar wind speed is presently about 420 km/s and the interplanetary magnetic field magnitude is 5 nT. It is not completely clear what is the magnetic structure observed in the in situ data, and reported yesterday. It seems like the arrival of the weak ICME was followed yesterday afternoon by the solar wind originating from the negative polarity coronal hole. The structure observed in the solar wind data did not induced disturbed geomagnetic conditions. The narrow and extended equatorial coronal hole of negative polarity has reached central meridian yesterday evening. The fast solar wind associated with this coronal hole might arrive to the Earth late on December 14. The geomagnetic conditions are presently quiet and we expect them to stay so in the coming hours.
