Bülten

NOAA 2731 produced a B1.0 flare in the past 24 hours, and has decayed to an alpha region. The chance for a C flare in the next 24 hours is estimated at 5%.

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 varied between about 300 and 350 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 and 4 nT. Bz was never below -5 nT. A weak solar wind stream associated with a negative polarity, equatorial-South polar coronal hole may arrive near Earth on December 16.

Quiet geomagnetic conditions (K Dourbes between 0 and 1; NOAA Kp between 0 and 1) were registered in the past 24 hours. There is a chance for active intervals (K Dourbes = 4) on December 16 and 17, related to the possible arrival of a weak solar wind stream associated with a negative polarity, equatorial-South polar coronal hole. Quiet to unsettled geomagnetic levels (K Dourbes < 4) are expected on December 18.
