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.
Jul 01, 2015: Switching to the new Sunspot Number

INFO FROM SIDC - RWC BELGIUM 2015 Aug 01 12:30UTC

Solar activity is low, no C-class flares in past 24 h. NOAA AR 2390 has
beta-gamma magnetic field configuration and could produce C-class flares.

The Earth is under the influence of a fast speed stream emanating from a
coronal hole, solar wind speeds are around 600 km/s with interplanetary
magnetic field magnitudes of 5 nT. Active conditions were observed
overnight and more active periods can be expected in the next 24 hours.
