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 Nov 11 12:30UTC

Solar activity was at very low levels, no significant flares have been
recorded. The Sun remained spotless. No earth-directed coronal mass
ejections (CMEs) have been observed in the available coronagraphic imagery.
The greater than 10 MeV proton flux was at nominal values.
Solar activity is expected to remain at very low levels.

The solar wind fluctuated around 310 km/s until 00:00 UT November 11, when
it began to gradually increase reaching a maximum of 370 km/s (ACE). The
total magnetic field initially fluctuated between 0 and 5 nT and then from
05:00 UT November 11 gradually increased to values up to 11 nT. Bz was
predominantly negative from 00:00 UT and reached a minimum value of -11
nT.
Geomagnetic activity was quiet for the first part of the period, following
which unsettled to active conditions were observed (Kp = 3 and local k
index Dourbes = 4) due to an extended period of strong negative Bz.

Unsettled conditions are expected over the next 48 hours due to the
influence of a negative polarity coronal hole.
