Additional Comments

Geomagnetic conditions are expected to reach elevated levels during the first forecast interval due to the anticipated arrival of a coronal mass ejection (CME) observed late on 26-Jun.
The faint CME seen on 27-Jun may arrive soon after, most likely in the second forecast window, which could further increase the already enhanced geomagnetic activity.
Overall ACTIVE conditions are expected with chances of STORM G2 periods.
Time of forecast: 30 Jun 2026
