Additional Comments

The arrival of the coronal mass ejection (CME) observed late on 30-Jun is still anticipated today and is likely to lead to an increase in geomagnetic activity with chances of STORM G2 intervals.
Enhanced geomagnetic conditions are expected to persist in the second forecast window due to possible glancing blows from several CMEs observed on 01-02 Jul.
The residual effects of these CMEs will then gradually wane into the third period.
