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 2014 Jul 27 12:28:41

Solar activity has been low with a couple of low level C flares from
Catania group 24 (NOAA AR 2123), the strongest one peaking at 13:20 UT at
C1.8 level and from NOAA AR 2125 (no Catania number) peaking at 5:51 UT at
C2.5 level.
Solar activity is expected to remain low over the next days with only a
slight chance for an M flare.
A CME was seen departing the west limb (visible in SOHO/LASCO C2 from
around 15:12UT), but it is not Earth directed.After reaching a maximum of
over 420 km/s at the start of the reporting period solar wind speed dropped
to under 340 km/s and is currently back at around 370 km/s. Total magnetic
field dropped from over 8nT to around 5nT with Bz variable within that
magnitude but currently mainly positive around 3nT. Geomagnetic conditions
have been quiet (NOAA Kp 1-2, local K Dourbes 0-3) with an isolated local
period between 18 and 21 UT.
Solar wind parameters are expected to remain nominal but to increase later
due to the influence of a coronal hole high speed stream. Geomagnetic
conditions are expected to be quiet first and later quiet to unsettled.
