Additional Comments

The solar wind speed is currently at background levels, and we anticipate it will remain low throughout the first forecast period.
The influence of a Coronal Hole (CH93) is expected to become geoeffective at the end of the second period and it likely sustain and enhanced solar wind speed past the end of this forecast. This enhancement increases the chances of geomagnetic activity with a low chance of seeing a STORM G1, depending on the solar wind conditions.
