Bülletään

The Sun is spotless and did not produce any flares in the past 24 hours. The chance for a C flare in the next 24 hours is estimated at only 2%.

No Earth-directed Coronal Mass Ejections (CMEs) were observed in available coronagraphic imagery.

The greater than 10 MeV proton flux was at nominal levels in the past 24 hours, and is expected to stay at nominal levels in the next 24 hours.

Solar wind speed near Earth as registered by DSCOVR decreased from about 480 to 395 km/s in the past 24 hours. The Interplanetary Magnetic Field (IMF) was predominantly directed towards the Sun and its magnitude varied between about 0.5 and 4 nT. Bz was never below -5 nT. Quiet solar wind is expected in the next 48 hours.

Quiet geomagnetic conditions (K Dourbes between 0 and 2; NOAA Kp between 0 and 2) were registered in the past 24 hours. Quiet to unsettled geomagnetic levels (K Dourbes < 4) are expected on December 13, 14 and 15.
