Except for a small magnetic dipole just passing the East limb in Extreme-UV images (probably a plage without sunspots), the Sun is featureless and is expected to remain inactive. Since early today, the solar wind has virtually vanished, reaching exceptionally low speeds (now at 250 km/s), low densities (< 0.1 electron/cm3) and low plasma temperatures (< 10⁴ K), based on ACE and SOHO/MTOF data. This leads also to exceptionally quiet geomagnetic conditions (Kp=0 at many ground stations). Those extremely quiet conditions certainly deserve special study. Only a weak solar wind stream expected tomorrow or on Dec.5 could restore more normal conditions, but just inducing temporarily unsettled geomagnetic conditions.
