Bülletään

Solar activity was very low over the last 24 hours. There are currently no sunspot regions on the visible solar hemisphere. 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 waning influence of the high speed stream (HSS) from the trans-equatorial extension from the negative southern polar coronal hole (CH). Solar wind speed declined from an initial range between 650 and 600 km/s to values between 520-560 km/s at the end of the period. Bz fluctuated between -5 nT and +5 nT. The interplanetary magnetic field was directed towards the Sun.

The geomagnetic field was at quiet to unsettled levels, and is expected to remain so. If the particle stream associated with the diffuse positive coronal hole arrives on 9-11 March, then an isolated active period is possible.
