G2 – Moderate Geomagnetic Storm Watch issued for June 14, 2026

A G2 – Moderate Geomagnetic Storm Watch has been issued for June 14, 2026. The alert was released by the NOAA Space Weather Prediction Center (SWPC) at 08:30 UTC, noting the potential for G2 – Moderate geomagnetic storm conditions to occur on this date.

Potential impacts from this event are expected to be primarily poleward of 55 degrees geomagnetic latitude. These impacts may include power grid fluctuations and possible voltage alarms in high-latitude power systems. Satellite operators may notice irregularities in orientation, and there could be increased drag on low Earth-orbit satellites. HF (high frequency) radio propagation could experience fading at higher latitudes. Additionally, auroral activity may be visible as far south as New York, Wisconsin, and Washington state.

The solar wind environment is currently influenced by a negative polarity coronal hole high speed stream (CH HSS) and the possible passage of coronal mass ejections (CMEs) that departed the Sun on June 9 and June 11. These factors are expected to contribute to the enhanced geomagnetic activity predicted for June 14, 2026.
