INFO FROM SIDC - RWC BELGIUM 2018 Nov 18 12:30UTC

There were no flares on the visible solar disc of the Sun in the past 24
hours. The chance for a C flare in the next 24 hours is estimated at 15%.

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.

In the past 24 hours, solar wind speed near Earth as registered by DSCOVR
varied between about 275 and 340 km/s, with current values around 330 km/s.
The Interplanetary Magnetic Field (IMF) was predominantly directed towards
the Sun and has increased from about 4 to 7.5 nT since 04:45 UT on November
18. This may be the first sign of the arrival of a solar wind stream from a
weak, negative polarity, equatorial coronal hole. Bz was never below -5
nT.

Quiet geomagnetic conditions (K Dourbes between 0 and 1; NOAA Kp between 0
and 1) were registered in the past 24 hours. Quiet to unsettled conditions
(K Dourbes < 4) are expected on November 18, 19 and 20, with a chance for
active intervals due to the possible arrival of a solar wind stream from a
weak, negative polarity, equatorial coronal hole.
