Additional Comments

Increased geomagnetic activity is expected during the second and third forecast interval due to the possible arrival of two coronal mass ejections (CMEs) observed on the 27th and 28th June. A CME that left the Sun on the 29th June is not believed to be Earth-directed.
Prolonged ACTIVE periods are anticipated with chances of STORM G1/G2 intervals.
Time of forecast: 30 Jun 2025
