The solar activity remained very quiet. The visible solar disc is spotless and no flare has been recorded in the past 24-hour. 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 High Speed solar wind Stream (HSS) associated with the Coronal Hole (which has crossed the central meridian on Dec 01) has arrived, and the wind speed has shown a gradual increased from its nominal level to the current level of about 550 km/s. Since the arrival of the Corotating Interaction Region announcing the HSS on Dec 04 around 15:00 UT, the interplanetary magnetic field magnitude has increased to fluctuate between 9-12 nT, and the Bz component has fluctuated between -12 and 10 nT. The solar wind conditions are expected to persist until while under the influence of the HSS associated with the coronal hole.

Disturbed geomagnetic conditions were observed due to the fast solar wind and the Bz component of the interplanetary magnetic field reaching -12 nT. A minor storm was observed by the local stations at Dourbes (K=5 from 19:00 to 20:00 UT on Dec 04), while NOAA reported Kp=5 at 12:00 UT on Dec 05. The high speed stream is expected to persist and further minor to moderate geomagnetic storms cannot be excluded, especially if Bz component remains negative for long period of time.
