Solar activity continues to be low without C-class flares reported since December 10. The only active region presently observed on the visible side of the solar disc, NOAA 2617, has approached to the west solar limb. We expect solar activity to stay at the same low level, and although the isolated C-class flares are possible they are not very probable. Newly available observations confirm that the CME, first seen in the SOHO LASCO C2 field of view at 06:48 UT on December 11, was a back side event and will therefore not arrive at the Earth. No Earth directed CMEs were observed in the last 24 hours.

The solar wind speed remains to be about 530 km/s, and the interplanetary magnetic field magnitude is presently about 4 nT. The fast solar wind associated with the small equatorial coronal hole which reached the central meridian yesterday morning is expected to arrive at the Earth in the midday of December 15. It might be closely followed in arrival time by the fast flow from the small coronal hole (between S08 and S12) which reached the central meridian early this morning. The geomagnetic conditions are presently quiet and we expect them to stay so in the coming hours.
