No C flares were observed in the past 24 hours. No C flares are expected in the next 24 hours. Solar wind speed further decreased from about 380 to 340 km/s in the past 24 hours as measured by DSCOVR. The magnitude of the Interplanetary Magnetic Field (IMF) varied between about 3 and 6 nT. A rise in solar wind speed is anticipated on December 31, due to the expected arrival of a high speed stream associated with a positive coronal hole. 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 levels (K Dourbes < 4) are expected on December 30. On December 31 and January 1, active intervals (K Dourbes = 4) are possible due to the expected arrival of a high speed stream associated with a positive coronal hole.
