Solar activity was at very low levels in the past 24 hours. No significant flares have been recorded. There are two numbered active regions on the solar disk, NOAA Active Region (AR) 2794 (alpha) and NOAA AR 2795 (beta). 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 exceeded the 1000 pfu threshold during the past 24 hours. The electron flux is expected to exceed this alert level again during the next period. The 24h electron fluence was at nominal to moderate levels and is expected to continue at nominal to moderate levels over the next 24 hours.

Over the past 24 hours, the solar wind speed showed an increasing trend with values mainly between 430 and 570 km/s (DSCOVR and ACE). The total magnetic field strength ranged between 1 and 8 nT. Bz had a minimum value of -6 nT. The interplanetary magnetic field was predominantly directed towards the Sun (phi angle in the negative sector). Over the next 24 hours, the solar wind parameters are expected to remain slightly elevated in response to the solar wind associated with the small, negative polarity coronal hole that crossed the central meridian on Dec 26.

Geomagnetic conditions were at quiet levels over the past 24 hours (NOAA Kp and local k Dourbes recorded values of 1-2). Geomagnetic conditions are expected to be at quiet to unsettled levels for the next 24 hours.
