Bülletään

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.
