Welcome to the Solar Influences Data Analysis Center (SIDC), which is the solar physics research department of the Royal Observatory of Belgium. The SIDC includes the World Data Center for the sunspot index and the ISES Regional Warning Center Brussels for space weather forecasting.

INFO FROM SIDC - RWC BELGIUM 2015 Jan 28 12:20:40

Four C- and one M-class flare were observed over the period. The strongest
event was an M1.4 flare peaking at 04:41 UT in NOAA 2268. Currently
available data and imagery suggest no CME was associated to this flare.
NOAA 2268 still has mixed magnetic polarities in its trailing portion. Old
active region NOAA 2257 is rounding the east limb. This is a complex group,
but produced only one minor C-class flare. No earth-directed CMEs have been
observed. The x-ray background flux was mostly above the C1-level. A 20
degree long filament near the solar equator is at W55 and thus in a
geoeffective position in case of eruption.

Further M-class flaring is expected.

Solar wind varied mostly between 440 and 500 km/s, with a peak of about 530
km/s around 03:00UT. Bz was mildly positive during the period, with
negative excursions between 19:00UT and 22:00UT (-5 nT) and again between
04:00 and 08:00UT (-7 nT). Geomagnetic conditions were mostly unsettled
with locally (Dourbes) some active episodes shortly after midnight.The
solar wind is expected to remain disturbed, with further influences from
the CH HSS and a possible glancing blow on 30 January from the 24 January
CME.

The geomagnetic field is expected to range from quiet to active
conditions.
