The SIDC is part of the Royal Observatory of Belgium and a partner in the Solar Terrestrial Center of Excellence (STCE).


There is one active region visible on the solar disk (NOAA 12735 with beta
magnetic field configuration). No C-class flares in past 24 h. Solar
activity is expected to remain low.
No Earth directed Coronal Mass Ejections (CMEs) have been detected. Solar
protons have remained at background levels over the past 24 hours.

The solar wind speed is at 375 km/s with interplanetary magnetic fields of
6 nT. Geomagnetic conditions have been quiet in the past 24 h. In the last
hours, density and interplanetary magnetic field started to increase,
together with a change of negative to positive IMF polarity. These are most
likely signs of the compression region in front of the high speed solar
wind stream expected for today. Unsettled to active geomagnetic conditions
can be expected (with possible isolated minor storm conditions).
