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 Nov 23 12:43:20

NOAA ARs 2209 and 2216 (Catania numbers 9 and 14 respectively) have
delta-spots in their trailing parts and continue to produce C-class flares.
However, the strongest flare of the past 24 hours was the C3.5 flare
peaking at 10:53 UT today in the still unnumbered sunspot group that
appeared from behind the east solar limb yesterday evening. We expect
flaring activity on the C-level, possibly with an isolated M-class flare. A
long filament in the northern hemisphere has finished crossing the solar
central meridian, but its eruption may still lead to an Earth-directed
CME.The Earth is currently inside a slow (around 400 km/s) solar wind flow
with slightly elevated (7-8 nT) interplanetary magnetic field magnitude.
Due to low solar wind speed, the geomagnetic conditions remained mostly at
the quiet to unsettled level (K < 4), only with one interval of active
conditions (K = 4) reported by IZMIRAN and NOAA yesterday evening. The
geomagnetic conditions are expected to stay at the quiet to unsettled
levels (K < 4), with isolated intervals of active conditions (K = 4).
