INFO FROM SIDC - RWC BELGIUM 2015 Feb 01 12:19:45

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.
