Bülletään

During last 24 hours NOAA AR 2733 was source of B-class flares, and an isolated GOES C5.0 flare (peaked at 13:22 UT on January 26). The NOAA AR 2733 is approaching the West solar limb, but it still has beta configuration of its photospheric magnetic field and is expected to be the source of B-class and possibly also isolated C-class flares in the coming hours. There were no wide Earth directed CMEs reported during last 24 hours. The solar protons remained at the background level.

The solar wind speed continues to decrease and it presently amounts about 430 km/s. The interplanetary magnetic field magnitude is 4 nT. Equatorial coronal hole of negative polarity reached central meridian this morning. Coronal hole is very patchy, but rather large and possibly connected with the southern polar coronal hole. The associated fast solar wind might be expected at the Earth on January 30. The geomagnetic conditions are presently quiet to unsettled and we expect quiet geomagnetic conditions in the coming hours.
