Bülletään

No C-class flares were observed during the last days. Two sunspot groups are currently visible on the Sun according to the SDO/HMI data. Their small size makes a C-class flare in them unlikely. A filament eruption in the south-eastern quadrant of the solar disk was detected by SDO/AIA starting around 01:30 UT today. It was associated with the B4.1 flare peaking at 05:25 UT. The corresponding CME seems to be weak and narrow, so it is not expected to arrive at the Earth. A low-latitude coronal hole in the northern hemisphere reached the solar central meridian yesterday. It is, however, small, so the Earth will most probably only skim the edge of the corresponding fast flow on September 13. The Earth is currently inside a slow (around 340 km/s) solar wind flow with average (4-5 nT) interplanetary magnetic field magnitude. We expect quiet geomagnetic conditions in the coming hours.
