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.

Solar Eclipse, March 20, 2015

INFO FROM SIDC - RWC BELGIUM 2015 Mar 26 11:53:51

Solar activity remains low with only few C-class flares reported during the
last 24 hours. The strongest reported flare was a C3.3 flare on March 25
(peak at 16:45 UT) originating from the Catania sunspot group 13 (NOAA AR
2305). This active region maintains the beta-gamma-delta configuration of
its photospehric magnetic field and therefore still has the possibility for
producing C-class and M-class flares in the course of coming hours. No
Earth directed CMEs were observed during last 24 hours.The solar wind speed
decreased to the value of about 450 km/s and the interplanetary magnetic
field is stable with the magnitude of about 6nT. The geomagnetic conditions
are at the moment quiet, we expect quiet to unsettled geomagnetic
conditions in the following 24 hours.
