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 25 12:27:23

Solar activity has been mostly quiet except for Catania group 22 (NOAA AR
2121) which did produce another C2 flare peaking at 7:02 UT. The background
X-ray flux rose slightly to around the B3 level. Similar conditions
(essentially quiet but with a significant chance for an occasional low
level C flare) are expected to continue with an increasing C flare
probability as some returning active regions are turning into view over the
next days. These will eventually also raise a slight chance for M level
No Earth directed CME's have been observed.After reaching maxima of just
over 400km/s at the start of the reporting period, solar wind speed
decreased to a minimum of about 310 km/s and later increased again
gradually to values presently about 360 km/s. The total magnetic field
varied essentially in the 2 to 6.5 nT range with Bz also variable in the
+-6nT range. Geomagnetic conditions were quiet to unsettled (local K
Dourbes 2-3 and NOAA Kp 1-3). Similar solar wind conditions as well as
geomagnetic conditions (quiet to unsettled) are expected to continue over
the next days.
