Solar activity has been at active levels over the last 24 hours. 9 C- and 3 M-class flares were recorded. The 3 M-class flares all originated in the mixed polarity region south of NOAA 1967's main spot, the strongest reaching M4-level at 19:40UT. This part of the region has been increasing its sunspot area. The mixed polarity region to the northwest of the main spot produced C-class flares as well as an M3-spike at 15:26UT (total duration less than 4 minutes), after which it simplified. NOAA 1968 was responsible for 2 C-class flares originating in its trailing portion. A filament eruption took place to the north and west (trailing) of NOAA 1960. It was associated to a C4-flare peaking at 00:49UT. The x-ray background has been all day above the C1-level. Active conditions are expected to continue, with a slight chance on an X-class flare. The CMEs associated with NOAA 1967's flaring activity were directed to the East and away from Earth. The CME from the filament eruption was directed mostly to the South and away from Earth. Based on current imagery, no geomagnetic effects are expected from these CMEs. Around 20:30UT, solar wind speed changed from about 330km/s to 450-500 km/s. The high temperature, low density stream had a Bz varying between -5 and +5 nT. The source of this high speed stream is most probably a small coronal hole that passed the central meridian on 25 January. Geomagnetic effects were limited and quiet conditions persisted. Solar wind may continue to be modulated by the effects of small coronal holes that have passed the central meridian on 27 and 29 January. Geomagnetic conditions are expected to remain quiet.
