Additional Comments

Overall QUIET geomagnetic conditions are expected.
Possible lingering effects of the recent coronal mass ejection (CME) passing might bring some brief ACTIVE intervals early in the first forecast period.
Glancing impact from CMEs associated with filament eruptions observed on 03-Aug is anticipated on 07-Aug, although further analysis is required.
