Five C- and one M-class flare were observed over the period. The strongest event was an isolated M1.1 flare peaking at 16:53 UT in NOAA 2268. This sunspot group still has some mixed magnetic polarities in its trailing portion. Newly numbered AR NOAA 2273 and NOAA 2275 also show some magnetic mixing in resp. their trailing and middle portion. Old active region NOAA 2257 is heralding its approach at the NE limb with increased flaring and CME activity. No earth-directed CMEs have been observed. The 10.7 cm radio-flux jumped from 127 sfu on 25 January to 147 sfu on 26 January, with the x-ray background flux now near the C1-level. A 20 degree long filament near the solar equator is at W40 and thus in a geoeffective position in case of eruption. There's a chance on another M-class flare. Solar wind was steady at 370 km/s till 01:00UT before gradually increasing to a maximum speed just over 500 km/s around 07:00UT. It is currently near 440 km/s. Bz varied between -9 nT and +6 nT, and is now fluctuating between -5 and +3 nT. Solar wind parameters were indicative of a HSS from a CH. Geomagnetic conditions were quiet to unsettled. A small equatorial CH transited the CM on 25 January and may influence the geomagnetic field on 29 January. The geomagnetic field is expected to range from quiet to active conditions.
