Additional Comments

Solar wind speed remains slightly enhanced above background levels due to residual coronal hole influence but we do not anticipate any significant geomagnetic activity during day one.
The previously mentioned CME associated with the M3.3 flare on the 21st may still give a weak glancing blow, likely later during day two and may produce an occasional ACTIVE spell, perhaps peaking briefly at STORM G1.
A further CME linked to a filament eruption after the M1.3 flare yesterday appears to have a more significant Earth-directed component. Although initial analysis suggests the bulk of the material will pass south of Earth, this is still expected to bring further ehnancement to activity levels with ACTIVE periods likely during day three and some periods of STORM G1 possible, perhaps even peaking at STORM G2 levels.
