Bülletään

The strongest flare reported in last 24 hours is still ongoing C5.2 flare (peaked at 11:53 UT). The flare seem to originate from the NOAA AR 2166. Two eruptions of filaments situated at the center of the solar disc, on September 20 (at about 06:00 UT) and on September 21 (at about 02:10 UT), did not seem to be associated with wide CMEs. Majority of the recent flaring activity originated from NOAA AR 2171 and NOAA AR 2172 currently situated close to the east solar limb. We expect C-class flares and possibly also an isolated M-class flare in the coming hours, in particular from these two active regions. The solar wind speed remains to have value of about 520 km/s. The interplanetary magnetic field magnitude is stable with the value of 4 nT. The geomagnetic conditions are quiet and expected to remain so in the following 48 hours.
