Additional Comments

Solar wind speed continues to decline as Coronal Hole influence wanes. The next High Speed Stream is anticipated to become geoeffective during day two, although we do not expect any significant enhancement from this. A CME associated with an M-class flare may still give a weak glance, also on day two and this in combination with the High Speed Stream could bring some ACTIVE periods, perhaps peaking at STORM G1.
Further M and X-class flares and associated CMEs have been observed over the past 24 hours, but given their location they are unlikely to have any significant Earth-directed component, if any, although confirmation of this is pending further imagery and analysis.
