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 only 2%.

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 early UT hours of December 17, the solar wind near Earth as observed by DSCOVR showed the first signs of influence from an anticipated solar wind stream associated with a negative polarity, equatorial-South polar coronal hole. After a rise in solar wind density, the Interplanetary Magnetic Field (IMF) rose to a maximum of around 12 nT. Meanwhile, the solar wind speed has increased from about 300 to 440 km/s. The Interplanetary Magnetic Field (IMF) was predominantly directed towards the Sun and its magnitude has current values around 6 nT. Bz was never below -6 nT.

Quiet geomagnetic conditions (K Dourbes between 0 and 2; NOAA Kp between 0 and 2) were registered in the past 24 hours. There is a chance for active intervals (K Dourbes = 4) on December 17 and 18, related to the arrival of a solar wind stream associated with a negative polarity, equatorial-South polar coronal hole. Quiet to unsettled geomagnetic levels (K Dourbes < 4) are expected on December 19.
