Additional Comments

The geomagnetic environment is currently QUIET, and solar wind conditions remain at background levels.
We anticipate the arrival of a High-Speed Stream (HSS) from a recurrent trans-equatorial coronal hole late in the first forecast period or early in the second. The HSS is expected to enhance solar wind speeds and lead to an increase in geomagnetic activity, with conditions potentially reaching minor storm levels (STORM G1)
