Solar activity was low, with only a single C-class flare peaking at 18:06 at C1.2 level from NOAA AR 2790. NOAA AR 2786 is rotating off the disk. This leaves on disk only NOAA AR 2790, of beta type and source of the mentioned C1.2 flare together with the newly numbered region NOAA AR 2791, also of beta type but mostly inactive and seemingly in decay. Further isolated C flaring is possible in the next 24 h.

No new Earth-directed CMEs have been observed in coronagraph data.

An elongated equatorial coronal hole of negative polarity is currently transiting the central meridian and expected to influence Solar wind conditions from December 9 onwards.

The greater than 10MeV proton flux is at background levels and is expected to remain at background levels. The greater than 2MeV electron flux did not exceed the 1000 pfu alert threshold. The 24h electron fluence was at moderate levels and is expected to remain at normal to moderate levels over the next days.

Solar wind conditions were near nominal with solar wind speed in the 300-400 km/s range and the interplanetary magnetic field mostly around a nominal 5nT, with a variable and unremarkable North-South orientation. The magnetic field phi angle has been variable since the start of the period. There are no signs of any influence of the December 1 CME, ans this is now not expected anymore. Essentially nominal Solar wind conditions are expected over the next days until December 9 when we are expected to see the onset of a high speed stream from the equatorial negative polarity coronal hole..

Geomagnetic conditions were quiet (local K Dourbes 0-2 and NOAA Kp 1-2). Geomagnetic conditions are expected to be quiet.
