Bulletin

In the past 24 hours, there were no spotted regions on the Sun, and not a single flare was observed. Very low solar activity (no C flares) is expected in the next 24 hours. Solar wind speed measured by DSCOVR varied between about 610 and 740 km/s in the past 24 hours under the influence of a positive coronal hole high speed stream, while the magnitude of the Interplanetary Magnetic Field (IMF) varied between about 3 and 6 nT. The influence of the high speed stream is expected to continue in the next 24 hours. Quiet to active geomagnetic conditions (K Dourbes between 2 and 4; NOAA Kp between 2 and 5) were registered in the past 24 hours. Quiet to active levels (K Dourbes < 5) are expected on December 26 and 27, with a slight chance for minor storm episodes (K Dourbes = 5). Quiet to unsettled levels (K Dourbes < 4) are expected on December 28.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 000, basierend auf 25 Stationen.
