Bülten

Solar X ray flux remained below B level throughout the period. Apart from some very short lived spots, the visible disk was spotless and X-ray flux is expected to remain at background levels.

No Earth-directed CME's were detected in coronagraph images.

Solar high energy proton fluxes were at background levels and are expected to remain so. The >2MeV electron flux is enhanced (though not over the event threshold) as a consequence of the high speed stream passage but expected to slowly start a gradual return to background values.

Solar wind further returned to nominal, with Solar wind speed decreasing from around 390 km/s to under 340 km/s and total magnetic field in the 4-6nT regime. The magnetic field phi angle was in the positive sector. Solar wind conditions are expected to remain nominal in the coming days with later on December 24 a possible weak enhancement associated to the low latitude negative polarity coronal hole in the Southern hemisphere.

Geomagnetic conditions were quiet (both local K Dourbes and NOAA Kp 0-2) and this is expected to persist. From later December 24 we expect a slight increase to quiet to unsettled conditions.
