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


Solar X-ray flux remained below B level.
As NOAA region 2727 is in decay, chances for C-flares are further reduced
and very low.

No Earth directed CMEs have been observed in coronagraph images.

Proton flux levels were at background values and are expected to remain

Solar wind went through a period of increased interplanetary magnetic field
to just over 10nT which announced a period of rise in Solar wind velocity
to currently close to 440 km/s. This is indicative of a mild influence from
a high speed stream from the Southern negative polarity coronal holes. It
remains to be seen if it's influence will set true more clearly.
Slightly enhanced solar wind conditions are hence expected to continue.

Geomagnetic conditions were quiet to unsettled (NOAA Kp 0-3, and local K
Dourbes 1-3) and are expected to continue under the slightly enhanced Solar
wind conditions.
