Additional Comments

The solar wind speed is currently just above background levels, and no significant enhancement is anticipated during the first forecast period.
A High-Speed Stream (HSS) associated with Coronal Hole CH73 is expected to become geoeffective late in the second period or early in the third. This is likely to result in intervals of minor (STORM G1) geomagnetic storm conditions.
