Additional Comments

The geomagnetic environment is currently QUIET, although solar wind speeds remain elevated at just below 500 km/s, increasing the likelihood of ACTIVE intervals.
Geomagnetic activity is expected to remain QUIET during the first forecast period. A Coronal Mass Ejection (CME) is anticipated to arrive during the second forecast period. This is expected to result in geomagnetic activity reaching up to STORM G2 levels. Activity is then expected to gradually decline during the third forecast period as CME effects wane.
