INFO FROM SIDC - RWC BELGIUM 2019 Oct 23 12:30UTC

Solar X ray flux remained below B level throughout the period.
There are no active regions on disk and X-ray flux is expected to remain at
background levels.

The filament eruption reported yesterday did not have any noticeable CME
associated.
No Earth-directed CME's were detected in coronagraph images.

Solar high energy proton fluxes were at background levels and are expected
to remain so.

Solar wind conditions were nominal, with Solar wind speed around 350 km/s
throughout the period and total magnetic field under 5nT. The magnetic
field phi angle was in the negative sector.
Solar wind is expected to increase significantly by tomorrow noon October
24 due to the recurrent high speed stream from an equatorial positive
polarity coronal hole.

Geomagnetic conditions were quiet (NOAA Kp 0-1 and local K Dourbes 0-2).
Geomagnetic conditions are expected to reach active levels with periods of
minor geomagentic storming associated to the expected high speed stream.
There is a chance that moderate storm levels (K=6) be reached.
