Solar flaring activity is low, with only few B-class and no C-class flares reported during last 24 hours. The only two numbered sunspot groups presently observed on the visible side of the solar disc are; decaying NOAA AR 2796, and NOAA AR 2797 which just rotated from the behind of the East solar limb. We expect a low level of flaring activity to persist in the coming hours. However, the NOAA AR 2797 still could be the source of occasional B-class and possibly, but not very probably also isolated C-class flare. During last 24 hours no Earth directed CMEs were observed in coronagraph data, and proton flux levels remained at background values.

Earth is still inside the slow solar wind with the speed of around 280 km/s, and the interplanetary magnetic field magnitude is about 5 nT. The arrival of the fast solar wind originating from the high latitude extension of the southern polar coronal hole can be expected later today or tomorrow. It might be followed by the fast solar wind associated with the low-latitude extension of the northern polar coronal hole (crossed the central meridian early on January 16). The geomagnetic conditions are presently quiet. The expected arrival of the fast solar wind can induce unsettled to possibly active geomagnetic conditions in the coming hours.
