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 275 and 325 km/s in the past 24 hours. The Interplanetary Magnetic Field (IMF) was directed towards the Sun, and its magnitude varied between about 2 and 8 nT. Bz was never below -5 nT. Quiet to mildly enhanced solar wind conditions are expected in the next 24 hours.

Quiet geomagnetic conditions (K Dourbes between 0 and 2; NOAA Kp between 0 and 2) were registered in the past 24 hours. Quiet to unsettled geomagnetic levels (K Dourbes < 4) are expected on December 31 and on January 1 and 2, with a chance for active intervals (K Dourbes = 4) due to the influence of a weak solar wind stream associated with a negative polarity coronal hole.
