Bulletin

In the past 24 hours, no C flares were observed. Very low solar activity (no C flares) is expected in the next 24 hours, with a slight chance for a C flare from new beta region NOAA AR 2644. Over the past 24 hours, solar wind speed measured by DSCOVR decreased from about 480 to 390 km/s, while the magnitude of the Interplanetary Magnetic Field (IMF) ranged between about 1 and 4 nT. Quiet geomagnetic conditions (K Dourbes between 0 and 2; NOAA Kp between 0 and 2) were registered in the past 24 hours. Quiet to unsettled geomagnetic conditions (K Dourbes < 4) are expected on March 26. The arrival of a high speed stream from a large, recurrent coronal hole is expected at the end of March 26 or the first half of March 27. Consequently, active to minor storm geomagnetic conditions (K Dourbes = 4 to 5) are possible on March 27 and 28, with a slight chance for moderate geomagnetic storm intervals (K Dourbes = 6).

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 024, basierend auf 17 Stationen.
