Bulletin

The Sun did not produce any C flares in the past 24 hours. The chance for a C flare in the next 24 hours is estimated at 15%. No Earth- directed Coronal Mass Ejections (CMEs) were observed in available coronagraphic imagery. The greater than 10 MeV proton flux was at nominal levels. Solar wind speed measured by DSCOVR jumped from 337 to 352 km/s at 2:45 UT on December 11, coinciding with a jump of the magnitude of the Interplanetary Magnetic Field (IMF) and the solar wind density. Solar wind speed has further increased to current values around 420 km/s. The IMF had a maximum around 12 nT at 7:26 UT, with current values around 8 nT. This enhanced solar wind is associated with the arrival of a high speed stream from a positive coronal hole that crossed the central meridian on December 8. Quiet to unsettled geomagnetic conditions (K Dourbes between 1 and 3; NOAA Kp between 0 and 3) were registered in the past 24 hours. Quiet to minor storm levels (K Dourbes < 6) are possible on December 11, 12 and 13 due to the influence of the high speed stream associated with a positive coronal hole, with a slight chance for moderate storm conditions (K Dourbes = 6).
