The solar activity remained very quiet. No flare has been recorded in the past 24-hour. One bipolar sunspot (Catania sunspot group 65) has just emerged. Quiet flaring conditions are expected.

No Earth directed Coronal Mass Ejection has been observed. The greater than 10 MeV solar protons flux remained at nominal levels over the past 24 hours and is expected to remain so.

The Earth remained under the high speed solar wind stream (HSS) associated with the Coronal Hole (which has crossed the central meridian on Dec 01). The wind speed has continued to gradually increase from 550 to 630 km/s, and is currently showing a slight declining to 540 km/s. The interplanetary magnetic field magnitude showed a slow decline from 11 nT to the current value of 4 nT, and the Bz component fluctuated between -8 and 6 nT to return to its nominal values between -4 and 4 nT.

Disturbed geomagnetic conditions were observed due to the fast solar wind and the Bz component of the interplanetary magnetic field reaching -8 nT. A minor storm was observed by the local stations at Dourbes (K=5 from 15:00 to 17:00 UT on Dec 05), while NOAA reported Kp between 3 and 4. The high speed stream is expected to persist and new minor geomagnetic storms cannot be excluded, especially if Bz component remains negative for longer periods of time.
