Bulletin

Solar activity is still low with the flaring at the C-class level. The strongest flare reported was C3.8 flare, peaking at 12:03 UT on September 20. All the C-class flares, in last 48 hours originated from the same NOAA AR 1850 which still has potential to produce C-class, and possibly M-class flares. Earth is inside the slow solar wind with the speed of about 410 km/s.The interplanetary magnetic field magnitude is stable having value of about 5 nT. The geomagnetic conditions are at the moment quiet. We expect quiet to active geomagnetic conditions in the following 48 hours due to the arrival of a fast flow (in the morning of September 22), associated with the low-latitude coronal hole in the northern hemisphere. The CME associated with the prominence eruption from September 19 is expected to arrive at the Earth on September 23.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 053, basierend auf 08 Stationen.
