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.

STCE annual meeting - 10y celebration & roof top tour, June 9

INFO FROM SIDC - RWC BELGIUM 2016 Jun 30 12:30UTC

Solar activity is very low with no C-class or even B-class flares reported
during last 24 hours. There are no active regions observed on the visible
side of solar disc.
We expect solar activity to remain low with possibly only occasional
B-class flare. No Earth directed CMEs were observed in the last 24 hours.

The solar wind speed is about 350 km/s, and the interplanetary magnetic
field magnitude is about 5 nT. The fast solar wind associated with the
elongated equatorial coronal hole (between N10 to S25), which has crossed
central meridian yesterday morning might arrive at the Earth in the morning
of July 2 and induce unsettled to active geomagnetic conditions.
