Solar activity was very low, with no flares observed during the period. The currently visible sunspot regions continue their decay. A small filament between NOAA 2628's stable leading spot and NOAA 2627 erupted in two steps. The northern part erupted between 24/0445 and 24/07:00UT January, the main part erupted between 24/0930 and 24/1130UT January. No obvious coronal dimming was observed. No earth-directed coronal mass ejections (CMEs) were observed in available coronagraphic imagery. The greater than 10MeV proton flux was at nominal levels.

Mostly quiet flaring conditions are expected, with a small chance on an isolated C-class event.

Solar wind speed declined from about 440 km/s to values near 320 km/s (ACE), with Bz fluctuating between -5 nT and +4 nT. The interplanetary magnetic field was mostly directed away from the Sun. A small positive equatorial coronal hole (CH) is transiting the central meridian.

The geomagnetic field was at unsettled to quiet levels and is expected to remain so. Starting around 27 January, the arrival of the CH's particle stream may affect the earth environment.
