Only low-level C-class flares were observed during the period. NOAA 2268 produced a long duration C2.8 flare peaking at 04:36UT, and the strongest event of the period at 11:33 UT (C3.2 flare). Despite continued decay in its sunspot area, NOAA 2268 still has a mixed magnetic polarity trailing portion and showed some increased flaring activity. NOAA 2277's leading portion shows important magnetic polarity mixing, but the region remained mostly quiet. The larger than 10 MeV proton flux is back at nominal levels. C-class flaring is expected, with a chance on an isolated M-class flare. Active conditions were observed in response to the arrival of the HSS from the southern polar CH around midnight. Solar wind speed increased from about 400 to just over 550 km/s at the end of the period, with Bz varying between -8 and +10 nT. Further influence of the HSS is expected over the next two days. The geomagnetic field is expected to range from quiet to active conditions, with a possibility of a minor geomagnetic storm.
