Additional Comments

Solar wind parameters are approaching background levels, and the anticipated glancing impact from a coronal mass ejection (CME) did not arrive. It is now very unlikely that this will cause any significant increase in geomagnetic activity.
A weak high speed stream may become geoeffective late in the first forecast interval. This is not expected to lead to a significant enhancement but there may be a slight chance for some brief, isolated periods of ACTIVE geomagnetic activity.
Conditions are expected to remain largely QUIET throughout all three forecast intervals.
