Bulletin

No C flares were observed in the past 24 hours. No C flares are expected in the next 24 hours. From 9h UT on December 31 onwards, solar wind speed gradually increased from about 300 km/s to about 370 km/s around 11:20 UT, when a shock in the solar wind was observed by DSCOVR. Current solar wind speed is around 470 km/s. The magnitude of the Interplanetary Magnetic Field (IMF) rose from around 3 nT to current values of about 14 nT. This is probably the effect of the arrival of the Coronal Interaction Region in front of the expected high speed stream associated with a positive coronal hole. Quiet geomagnetic conditions (K Dourbes between 0 and 2; NOAA Kp between 1 and 2) were registered in the past 24 hours. Active to minor storm geomagnetic levels (K Dourbes = 4-5) are expected on December 31. On January 1 and 2, active levels are expected (K Dourbes = 4), with a chance for minor storm intervals (K Dourbes = 5)
