Bülletään

Solar flaring activity remains low, with only isolated B-class flares reported. All the flaring activity originates from the NOAA AR 2797, the only numbered sunspot group presently observed on the visible side of the solar disc. We expect a low level of flaring activity to persist in the coming hours with occasional B-class flares. The isolated C-class flares are possible, but not very probable. During last 24 hours no Earth directed CMEs were observed in coronagraph data, and proton flux levels remained at background values.

The solar wind speed is presently around 320 km/s and it is slowly increasing. This increase might be due to the possible arrival of solar wind associated with the low latitude extension of the southern polar coronal hole. The interplanetary magnetic field magnitude is about 5 nT. The geomagnetic conditions are presently quiet and we expect quiet to unsettled geomagnetic conditions in the coming hours.
