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. 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 Earth environment is under the influence of the fastsolar
wind associated with the Coronal Hole (which reached the central meridian
on December 04). The wind speed continued to gradually increase and reached
the values around 610 km/s, it is now fluctuating around 510-560 km/s; The
interplanetary magnetic field strength fluctuated between 5 and 11 nT and
the southward magnetic component between -4 and 9 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 a short period of
active condition observed by the local station in Dourbes (K-Dourbs=4) on
December 8, at 15:00 UT. The conditions are expected to remain the same in
response to an enhanced interplanetary magnetic field, short periods of
active condition cannot be fully excluded especially if there is a
prolonged period of southward directed Bz component.
