Additional Comments

The geomagnetic environment is currently QUIET, and solar wind conditions remain at background levels.
A High-Speed Stream (HSS) from a recurrent trans-equatorial coronal hole is expected to become geoeffective during the first forecast period. The HSS is expected to enhance solar wind speeds and increase geomagnetic activity, with conditions potentially reaching STORM G1 levels. Activity is then expected to gradually decline, returning to QUIET levels by the end of this forecast.
