Bulletin

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 450 to 380 km/s in the past 24 hours as measured by DSCOVR. The magnitude of the Interplanetary Magnetic Field (IMF) varied between about 1 and 6 nT. A further decrease in solar wind speed is expected on December 29 and 30, while 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 1 and 2; NOAA Kp between 1 and 2) were registered in the past 24 hours. Quiet to unsettled levels (K Dourbes < 4) are expected on December 29 and 30. On December 31, active intervals (K Dourbes = 4) are possible due to the expected arrival of a high speed stream associated with a positive coronal hole.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 012, basierend auf 17 Stationen.
