Solar activity was at very low levels with the X-ray flux below B-class flare over the last 24 hours. Solar activity is expected to remain at low levels.

No Earth directed CMEs has been detected in the available coronagraph imagery.

The greater than 10 MeV proton flux was at nominal levels in the past 24 hours and is expected to remain at nominal levels in the next 24 hours. The greater than 2 MeV electron flux exceeded the 1000 pfu alert threshold in the past 24 hours but is expected to remain just below or at this threshold in the next 24 hours. The greater than 2 MeV electron fluence was moderate levels in the past 24 hours and is expected to be at between nominal and moderate levels in the next 24 hours.

The solar wind parameters (ACE+DSCOVR) are at background levels: the wind speed was ranging between 300 km/s and 365 km/s, the total magnetic field was below 5 nT, and its southward component, Bz, fluctuated between -4 nT and +3 nT in the past 24 hours . The interplanetary magnetic field phi angle was predominantly in the positive sector (directed away from the Sun). The solar wind is expected to continue to be at slow solar wind regime. The high-speed streams from the small equatorial coronal hole (negative polarity, north hemisphere) that traverse the central meridian on Dec 05 may slightly enhance the solar wind parameters near Earth later today around December 10-11. The high-speed streams associated to the other small equatorial coronal hole (negative polarity, south hemisphere, that crossed the central meridian on December 8) may also slightly enhance the solar wind parameters near Earth around December 12-13.

Geomagnetic conditions were quiet over the past 24 hours (NOAA Kp and K-BEL recorded values 0 to 2). Geomagnetic conditions are expected to remain quiet with possible isolated unsettled periods in response to the slightly elevated solar wind speed with the influence of the wind streams associated to the influences of small equatorial coronal hole.
