The solar activity has been at low levels over the past 24 hours. The sunspot group (Catania sunspot group 25, NOAA 2755) has now decayed. The X-ray flux is below B-level and solar activity is expected to remain at low levels for the next 24 hours.

Two narrow and relatively slow (about 150 km/s) coronal mass ejections were observed on the East and West limb, but no earth-directed components were identified in the available coronagraphic imagery.

The greater than 10 MeV proton flux was at nominal values.

The solar wind speed continued to decrease slowly from about 450 km/s to 354 km/s. The total magnetic field is below 5 nT, and the southern component of the magnetic filed was between -3 nT and 3 nT (as recorded by the ACE spacecraft). Today, starting around 11:10 UTC, weak enhancement of the solar wind can be observed with the wind speed increasing form 354 km/s to the current values of about 400 km/s. We anticipate further enhancements of the solar wind, in a couple of hours, due to the high-speed streams from the equatorial coronal holes that reached the central meridian on Jan 5.

Mostly quiet geomagnetic conditions were observed with Kp-index (NOAA) ranging between 0 and 2, and K-Dourbes between 0 and 3. Active geomagnetic conditions with a possible short-duration minor storm are expected with the arrival of the high-speed streams later today.
