INFO FROM SIDC - RWC BELGIUM 2018 Dec 15 12:30UTC

A new beta region, NOAA 2731, emerged in the past 24 hours. The Sun did not
produce any B flares or brighter in the past 24 hours. The chance for a C
flare in the next 24 hours is estimated at 5%.

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 DSCOVR varied between about
300 and 390 km/s in the past 24 hours. The Interplanetary Magnetic Field
(IMF) was predominantly directed towards the Sun and its magnitude varied
between about 2 and 6 nT. Bz was never below -5 nT. A weak solar wind
stream associated with a negative polarity, equatorial-South polar coronal
hole is expected to arrive near Earth on December 16.

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 geomagnetic
levels (K Dourbes < 4) are expected on December 15. There is a chance for
active intervals (K Dourbes = 4) on December 16 and 17, related to the
expected arrival of a weak solar wind stream associated with a negative
polarity, equatorial-South polar coronal hole.
