Additional Comments

Solar wind speed remains around background levels but this is expected to increase with the arrival of a coronal hole high speed stream later on day one or during day two. Geomagnetic activity should remain QUIET overall but with a chance of some occasional ACTIVE periods due to the coronal hole influence.
There is still a possibility of a weak glance from one or more CMEs, most likely during day two which may combine with the high speed stream to briefly push activity up to STORM G1. We cannot rule out a further occasional ACTIVE spell during day 3 due to ongoing coronal hole effects.
