Additional Comments

The coronal mass ejection (CME) from 6th June is believed to have missed the Earth, although late arrival cannot be fully ruled out just yet. Possible glance is still anticipated during the first forecast period, increasing the chances of brief STORM G1 intervals.
Geomagnetic conditions are expected to remain at mostly QUIET levels, followed by a further enhancement during the last forecast period due to the effects of a high-speed stream from a centrally located coronal hole.
