Bulletin

Solar activity was low. The Sun produced 2 low C flares in the past 24 hours. The brightest flare was a C1.7 flare released by NOAA AR 2595 with peak time 11:51 UT on September 21. Low solar activity (C flaring) is expected in the next 24 hours. Solar wind speed measured by DSCOVR decreased gradually from about 720 to about 550 km/s in the wake of a coronal hole high speed stream. Meanwhile the magnitude of the Interplanetary Magnetic Field varied beween about 1 and 6 nT. Quiet to active geomagnetic conditions (K Dourbes between 2 and 4, NOAA Kp between 2 and 4) were registered in the past 24 hours. Quiet to unsettled levels are expected on September 21, 22 and 23, with a chance for active levels (K Dourbes = 4) on September 21 as the influence of the coronal hole high speed stream wanes.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 056, basierend auf 13 Stationen.
