The solar activity remained quiet over the past 24 hours. No flare has been recorded. The unique sunspot (Catania sunspot group 65, NOAA Active Region 2690) on the visible disc showed a decay in magnetic complexity. Quiet flaring conditions are expected for the next 24-hour period.

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 solar wind speed has continued to gradually decrease from 530 km/s to 460 km/s. The interplanetary magnetic field magnitude remained below 5 nT, and the Bz component fluctuated between -4 and 4 nT. The solar wind conditions are expected to continue to decline and return to nominal conditions by tomorrow. A narrow northern polar coronal hole that extends down up to latitude 10-degree North is currently facing Earth. The high speed solar wind stream associated with this coronal hole is expected to reach Earth by Dec 11.

The geomagnetic conditions were globally quiet to unsettle with K-Dourbes and Kp ranging between 1 and 3, except on Dec 07 at 15:00 UT the local station at Dourbes reported active geomagnetic conditions (K-Dourbes = 4) for a short duration. The geomagnetic activity is expected to be quiet for the next following days until the arrival of the high speed stream on Dec 11.
