Bulletin

Solar activity was very low. The Sun produced no C flares in the past 24 hours. Low solar activity (C flaring) is possible in the next 24 hours, especially from beta-gamma region NOAA AR 2597. Solar wind speed measured by DSCOVR varied between about 350 and 390 km/s. Meanwhile the magnitude of the Interplanetary Magnetic Field increased from about 3 nT to current levels of around 11 nT. Quiet to active geomagnetic conditions (K Dourbes between 2 and 4, NOAA Kp between 1 and 5) were registered in the past 24 hours. Quiet to unsettled levels (K Dourbes < 4) are expected on September 25, with a chance for active episodes (K Dourbes = 4). Quiet to active levels (K Dourbes < 5) are expected on September 26 and 27 due to the expected arrival of a positive high speed stream associated with a negative coronal hole, with a chance for minor storm episodes (K Dourbes = 5).

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 028, basierend auf 19 Stationen.
