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 28 12:32:26

There are 8 relatively small sunspot groups visible. NOAA 2127, still close
to the southeast limb, and NOAA 2126 produced each one C1.2 flare (peaking
resp. at 14:18UT yesterday and at 11:45UT today). Both regions seem to have
some mixed magnetic polarity.  No Earth-directed CMEs were observed. Some
10-20 degrees long filaments are observed in the NE, SE and NW solar
quadrant, as well as in NOAA 2121. 

There's a chance on further C-class flaring, in particular from NOAA 2127
and 2126. An eruption of one of the filaments is possible.

A disturbance was observed in ACE solar wind data starting shortly after
03:00UT. Over the next four hours, wind speed gradually increased from 350
to 430 km/s, while Bz varied between +11 and -8 nT, being mostly positive
near the end of the period. The geomagnetic field was unsettled to locally
active in response to this disturbance.

Quiet to unsettled geomagnetic conditions are expected, with locally an
active period possible.
