Solar activity remained 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 stay at very low levels.

Solar wind parameters were at nominal levels until about 16UT, when solar wind became enhanced. Bz turned mostly southward and was at a steady -7 nT from 17UT till 21UT, with short-lived excursions to +8 nT and -9 nT just prior to 20UT (DSCOVR). This coincided with a more firm increase in temperature and speed, the latter gradually rising from about 340 km/s to 460 km/s at 08 UT. Currently, Bz is varying between -3 nT and +2 nT, with wind speeds steady near 440 km/s. The interplanetary magnetic field was predominantly directed towards the Sun. Geomagnetic activity was at quiet to unsettled levels, with an isolated active period observed in Kp (00-03UT) and by Dourbes (18-21UT).

Quiet to unsettled geomagnetic conditions are expected with a chance on another active episode. Minor storming intervals are possible on 24 and 25 March as a result of the expected arrival of the wind stream associated with the extension of the negative polarity southern polar CH.
