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 2013 May 20 12:00:22

Solar activity was eruptive with 7 C flares mostly originating from NOAA
1750 (Catania 78) and 1 M1.7 flare from an active region just behind the
east limb peaking on May 20th 05:25 UT. There is insufficient data
available to determine an associated CME, but chances for arrival on Earth
are very low due to its location.

Because the active region 1750 on the West limb can still produce M flares,
there is a possibility for a proton event.A shock corresponding to the CME
of May 17th arrived to the Earth at 22:23 UT on May 19 causing active
geomagnetic conditions (K Dourbes = 4).  

Geomagnetic conditions are currently quiet again and are expected to remain
so for the next 48 hours.
