Additional Comments

Solar wind speeds are currently slightly elevated, and the geomagnetic environment has returned to QUIET conditions following the weekend storm.
During the first forecast period, a coronal mass ejection (CME) that erupted on Saturday, June 6, is expected to arrive. This event is likely to enhance geomagnetic activity, with conditions reaching up to STORM G3 levels.
By the end of the forecast period, the solar wind environment is expected to gradually return to background levels.
