Numerous C- and 3 M-class flares were recorded over the last 24 hours, mostly originating from NOAA 1967. This region has three magnetic delta structures: two near the main spot, and one near the top of the region. The latter was the location of the strongest flare this period (M3 peaking at 07:23UT). One M-flare had NOAA 1968 as its source (M1 peaking at 15:42UT), which has developed more small spots of opposite polarity in its interior. This M1-flare was associated to a partial halo CME with a plane-of-sky
speed of 460 km/s. The bulk of the CME was directed to the northeast. The x-ray background has been all day above the C1-level. Active conditions are expected to continue, with a chance on an X-class
flare. Solar wind speed has been varying between 300 and 350 km/s and Bz fluctuating between -3 and +3 nT. Geomagnetic conditions were quiet.
For the next 24 hours, active geomagnetic conditions with a slight chance on minor storm levels are expected, in particular due to the arrival of the M6 CME (30 January) which is currently foreseen for the morning of 2 February. On 4 February, Earth may receive a glancing blow from the partial halo CME that originated in NOAA 1968 (31 January).
