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 31 12:23:20

Flaring activity declined with only a few low-level C-class flares, and the
strongest event produced by NOAA 2277 at the beginning of the period (M2.4
peaking at 12:16UT). NOAA 2268 simplified significantly. NOAA 2277 kept
most of its mixed magnetic polarity portions. No earth-directed CMEs have
been observed. The x-ray background flux has decreased to the B6-level. The
larger than 10 MeV flux is still enhanced, but started a gradual decline
after 21:00UT.

There remains a chance on an isolated M-class flare.

Solar wind speed ranged mostly between 390 and 450 km/s. Bz varied between
-7 and +7 nT, with a sustained negative period from 16:00 till 20:00UT.
Unsettled to locally active (K Dourbes = 4) conditions were recorded
between 18:00 and 24:00UT. The solar wind is expected to be further
disturbed with the arrival of the HSS of the extension of a southern polar
CH late on 31 January or on 01 February.

The geomagnetic field is expected to range from quiet to active conditions,
with a possibility of a minor geomagnetic storm.
