The solar activity has been quiet over the past 24 hours. The bipolar rather small sunspot group (Catania sunspot group 2, NOAA 2729) remained stable and did not produce any significant flare. Flaring conditions are expected to remain quiet with a very small chance 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 measurements indicated the onset of a Corotating Interaction Region announcing the soon arrival of the solar wind High Speed Stream associated with the Coronal Hole (which reached the central meridian on November 27). The wind speed shows a gradual increase from the nominal values (around 368 km/s) to the values of about 475 km/s. The interplanetary magnetic field strength has shown an increase on Dec 7 around 04:00 UT due to the arrival of a CIR: the total magnetic field reached 11.6 nT at 06:00 UT on Dec 7; and the southward component reached negative value of -9.9 nT. The enhanced solar wind conditions are expected to persist 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 over the past 24 hours. The conditions are expected to become more active in response to an enhanced interplanetary magnetic field, especially if there is a prolonged period of southward directed Bz component.
