Bulletin

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 remained below the 1000 pfu alert threshold and is expected to remain below this level during 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 speed (DSCOVR) started to slowly decay from 500 km/s to 400 km/s over the past 24 hours, the total magnetic field was below 9 nT, and its southward component, Bz, fluctuated between -4 nT and +4 nT. The interplanetary magnetic field phi angle was predominantly in the positive sector (directed away from the Sun). The solar wind is expected to gradually return to a slow solar wind regime later on Dec 08 and 09. 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 around December 10-11. Another small equatorial coronal hole (negative polarity, south hemisphere) is currently crossing the central meridian, the high-speed streams associated to this coronal hole may 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 1-2). Geomagnetic conditions are expected to be quiet.

Today's estimated international sunspot number (ISN): 012, based on 12 stations.
