Bülletään

Only 2 minor C-class flares were observed during the last 24 hours. The strongest was a C1.8 flare peaking at 06:27UT in steadily growing NOAA 2271. Some new flux emerged in the trailing portion of NOAA 2268. Both this region and NOAA 2271 have some mixed magnetic polarities. The other regions were quiet. No Earth-directed CMEs were observed. A 20 degree long filament near the solar equator is at W30 and thus in a geoeffective position in case of eruption. C-class flaring is expected, with a chance on an isolated M-class flare. A disturbance in the solar wind was recorded starting 25 January around 20:00UT. Bz fluctuated between +9 and -15 nT, wind speed increased slightly and varied between 350 and 400 km/s. Elevated particle densities (20-40 particles per cm3) were observed between 05:00UT and 10:00UT. This may herald the arrival of a CH HSS, but further data are required to confirm this. Both Kp as K Dourbes recorded active geomagnetic conditions. A small equatorial CH transited the CM on 25 January and may influence the geomagnetic field late on 28 January. The geomagnetic field is expected to be unsettled to active.
