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

INFO FROM SIDC - RWC BELGIUM 2019 Oct 18 12:30UTC

The Sun is spotless and did not produce any flares in the past 24 hours.
The chance for a C flare in the next 24 hours is estimated at only 1%.

No Earth-directed Coronal Mass Ejections (CMEs) were observed in available
coronagraphic imagery.

The greater than 10 MeV proton flux was at nominal levels in the past 24
hours, and is expected to stay at nominal levels in the next 24 hours.

Solar wind speed near Earth as registered by ACE varied between about 330
and 420 km/s in the past 24 hours. The Interplanetary Magnetic Field (IMF)
was predominantly oriented away from the Sun and its magnitude varied
between about 1 and 6 nT. Bz was never below -5 nT. Enhanced solar wind
conditions are expected from the second half of October 19 onwards, with
the expected arrival of a high speed stream associated with a recurrent,
negative polarity, narrow coronal hole that spans from the South pole to
the equator.

Quiet to unsettled geomagnetic conditions (K Dourbes between 1 and 3; NOAA
Kp between 1 and 2) were registered in the past 24 hours. Quiet to
unsettled geomagnetic levels (K Dourbes < 4) are expected on October 18 and
the first half of October 19. Active to minor storm intervals (K Dourbes =
4-5) are possible in the second half of October 19 and on October 20 (with
a chance for moderate storm intervals, K Dourbes = 6), due to the expected
arrival of a high speed stream associated with a recurrent, negative
polarity, narrow coronal hole that spans from the South pole to the
equator.
