Bülten

The Sun is spotless and did not produce any B flares or brighter 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.

The solar wind speed near Earth as registered by DSCOVR varied between about 390 and 455 km/s in the past 24 hours. The Interplanetary Magnetic Field (IMF) was predominantly directed towards the Sun and varied between about 2 and 8 nT. Bz was never below -6 nT. Solar wind speed is expected to decrease on December 18 and may increase again to moderate values on December 19 due to the solar wind stream from an isolated negative polarity coronal hole.

Quiet geomagnetic conditions (K Dourbes between 1 and 2; NOAA Kp between 1 and 3) were registered in the past 24 hours. There is a chance for active intervals (K Dourbes = 4) on December 18 and 19. Quiet to unsettled geomagnetic levels (K Dourbes < 4) are expected on December 20.
