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 is gradually exiting the high speed stream (HSS) from a negative polarity coronal hole (CH). During the period, solar wind speed decreased from 520 km/s to 450 km/s (DSCOVR). Bz oscillated between -4 and +4 nT, with a short-lived excursion to -6 nT around 19UT. The interplanetary magnetic field was mostly directed towards the Sun. Geomagnetic activity ranged from quiet to unsettled, with local K indices (Wingst, Niemegk) reaching active levels during the 21-24UT interval.

Over the next few days, quiet to unsettled conditions are expected with a chance on an active episode from wind streams associated with the patchy equatorial CHs and the leading extension from the negative polarity southern polar CH. 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 from the southern polar CH.
