Solar activity was at very low levels in the past 24 hours. No significant flares have been recorded. NOAA Active Region (AR) 2794 (alpha) and NOAA AR 2795 (beta) remained stable. Solar activity is expected to remain at low levels, with a low probability of C-class flares.

No Earth directed Coronal Mass Ejections (CMEs) have been detected in the available coronagraphic imagery.

The greater than 10 MeV proton flux was at nominal levels in the past 24 hours and is expected to remain so in the next 24 hours. The greater than 2 MeV electron flux remained just below the 1000 pfu alert threshold. The electron flux is expected to remain below this level during the next period. The 24h electron fluence was at nominal levels and is expected to remain so over the next 24 hours.

Over the past 24 hours, the solar wind speed varied between 420 and 520 km/s (DSCOVR and ACE). The total magnetic field strength ranged between 1 and 7 nT. Bz had a minimum value of -5 nT. The interplanetary magnetic field was predominantly directed towards the Sun (phi angle in the negative sector), with a few short deviations into the positive sector. Over the next 24 hours, the solar wind parameters are expected to remain slightly enhanced before gradually decreasing to nominal values from Dec 30.

Geomagnetic conditions were at quiet to unsettled levels over the past 24 hours (NOAA Kp and local k Dourbes recorded values of 1-3 and 1-2, respectively). Geomagnetic conditions are expected to be at quiet levels for the next 48 hours with the possibility of an isolated unsettled interval.
