Additional Comments

A minor shock in the solar wind arrived this morning due to the late arrival of the anticipated coronal mass ejection. Geomagnetic activity is QUIET so far with a chance of ACTIVE spells if the solar wind conditions develop further.
High speed solar wind from coronal hole influences should arrive from the second forecast interval onwards. This could raise geomagnetic activity to ACTIVE or STORM G1 levels.
