NOAA AR 2790 is the only visible active region on the solar disc, it did not produce any C-class flares or larger in the past 24 hours. C flaring is possible, but unlikely, in the next 24 h.

No Earth directed CMEs were detected in the past 24 hours.

An equatorial coronal hole of negative polarity crossed the central meridian on 6 December, its associated high speed stream (HSS) is expected to arrive to the Earth in the next 24 hours. It consists of several small coronal holes patches, it will probably not have a large impact.

The greater than 10 MeV 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, it may increase with the arrival of the HSS. The 24h electron fluence was at moderate levels, it may increase with the arrival of the HSS.

Solar wind speed ranged between 350 km/s and 400 km/s and the interplanetary magnetic field was around 5 nT in the past 24 hours. Bz never went below -5 nT. The magnetic field phi angle has oriented towards the Sun (negative).

Geomagnetic conditions were quiet to unsettled (local K Dourbes 0-2 and NOAA Kp 0-3). Geomagnetic conditions are expected to increase in the next 24 hours due to the arrival of the HSS and the halo CME from 7 December, active to moderate storm periods can be expected.
