Additional Comments

Solar wind speed is continuing to decline towards background levels and geomagnetic activity should be QUIET for the next day or so, before the High Speed Stream from a northerly coronal hole becomes geoeffective on day two. Some ACTIVE periods are to be expected as a result, with perhaps a chance that it could peak briefly at STORM G1. Some further ACTIVE periods may be possible on day three due to ongoing Coronal Hole influence. There are currently no known Earth-directed CMEs.
