The solar activity has been quiet over the past 24 hours. The bipolar sunspot group (Catania sunspot group 2, NOAA 2729) remained globally stable and did not produce any significant flare. A new region is visible on the East limb, but so far do not show any strong activity. Flaring conditions are expected to remain quiet with a very small change of C-class flare.

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 environment is under the influence of the enhanced solar wind associated with the Coronal Hole (which reached the central meridian on December 04). The wind speed continued to gradually increase from about 425 km/s to reach the values around 570 km/s ; The interplanetary magnetic field strength fluctuated between 5 and 10 nT and the southward magnetic component between -7 and 6 nT being mainly positive. The enhanced solar wind conditions are expected to persist in the following days as long as Earth remains under the influence of the solar wind associated with the coronal hole.

The geomagnetic conditions were quiet to unsettled with short periods of active condition observed by the local station in Dourbes (K-Dourbs=4) on December 7, at 20:00 UT and 21:00 UT. The conditions are expected to remain the same in response to an enhanced interplanetary magnetic field, short periods of active condition are possible especially if there is a prolonged period of southward directed Bz component.
