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 31 12:32:30

There are currently 8 sunspot groups present on the solar disk. NOAA 2127
produced most of the flares including a C9 flare peaking at 16:17UT (30
July). Overnight, NOAA 2130 developed a delta spot south of its trailing
portion and started producing flares again around 05:00UT. This culminated
in an M2.5 flare peaking at 11:14UT, the strongest event of the period.
Evaluation of any associated CME is pending the availability of
coronagraphic images. 
Yesterday's filament eruption (NE quadrant) was associated to a CME which
may have an Earth directed component. Based on STEREO and SOHO imagery, its
true speed is estimated to be about 800 km/s and may affect the geomagnetic
field on 2 August. The filaments near the NE-limb and in the SW solar
quadrant are stable.

Further M-class flaring is possible, in particular from NOAA 2127 and
2130.

Solar wind speed varied between 300 and 350 km/s, and Bz between -3 and +4
nT. Quiet geomagnetic conditions were observed. A small equatorial coronal
hole is approaching the central meridian and may influence the geomagnetic
field around 4 August. 

Quiet geomagnetic conditions are expected until 2 August, when the CME
related to the 30 July filament eruption may deliver a glancing blow and
result in active geomagnetic conditions.
