Solar activity was very low during the period. The solar disk is currently devoided of sunspots. A small active region is about to rotate over the east limb. No earth-directed coronal mass ejections (CMEs) were observed in available coronagraphic imagery. The greater than 10MeV proton flux was at nominal levels.

Quiet flaring conditions are expected to continue.

Earth remained under the influence of the high speed stream (HSS) from the trans-equatorial extension from the negative southern polar coronal hole (CH). Solar wind speed varied between 650 and 550 km/s, with Bz mostly fluctuating between -5 nT and +6 nT. The interplanetary magnetic field was directed towards the Sun. A diffuse positive equatorial CH is transiting the central meridian.

The geomagnetic field ranged from quiet to active levels, with a minor storming episode reported during the 18-21UT interval. Mostly quiet to active geomagnetic conditions are expected, with still a chance on a minor storming interval. The particle stream associated with the positive CH is expected to arrive around 9 March resulting in only unsettled to active conditions.
