Additional Comments

Solar wind speed has declined to near background levels and geomagnetic activity is expected to be QUIET overall for the next couple of days.
The High Speed Stream from a northerly Coronal Hole is anticipated to become geoeffective later on day three, and although we do not expect a significant increase in activity based on the previous rotation, some ACTIVE periods may still be possible with a slight chance it could peak briefly at STORM G1.
A small CME was observed yesterday, and while initially it appears that the bulk of it will miss Earth, we are awaiting further analysis to determine if there may be any Earth-directed component.
