Bülletään

Solar activity was at very low levels. The Sun is spotless. No earth-directed coronal mass ejections (CMEs) were observed in available coronagraphic imagery. The greater than 10 MeV proton flux was at nominal levels.

Solar activity is expected to remain at very low levels.

Earth has left the coronal hole (CH) wind stream. Current solar wind parameters are at nominal levels. Solar wind speed decreased from 450 km/s to 330 km/s, and Bz varied mostly between -3 and +3 nT (DSCOVR). The interplanetary magnetic field was directed mostly away from the Sun before midnight, and mostly towards the Sun after midnight. Geomagnetic activity was at quiet levels.

Over the next few days, quiet to unsettled geomagnetic conditions are expected with a chance on an active episode from wind streams associated with the patchy equatorial CHs. The chance on an isolated minor storming interval is likely to increase by 24-25 March with the expected arrival of the wind stream related to the more prominent trailing extension of the southern polar CH.
