Additional Comments

The solar wind speed is currently elevated; however, the magnetic field carried by the solar wind has shown only a weak north–south component, resulting in a QUIET geomagnetic environment. Any increase in the southward component of this field could lead to a corresponding rise in activity.
We anticipate the arrival of an additional High-Speed Stream (HSS) from coronal hole CH15 to become geoeffective during the third forecast period, further increasing solar wind speed and raising the likelihood of isolated intervals of geomagnetic activity.
