Geomagnetic storm forecast - 8th June 2026

We are expecting an increase in geomagnetic activity today, 8^th June 2026.

Geomagnetic conditions were elevated on 4^th June due to a solar flare and associated coronal mass ejection (CME) that lifted off the Sun on 3^rd June. While activity has since returned to QUIET levels, solar wind speeds remain slightly elevated. We are now expecting a further increase in geomagnetic activity today (8^th June) as another CME, which lifted from the Sun on Saturday 6^th June, arrives at Earth. This incoming CME is anticipated to drive an enhancement in activity, with STORM G3 periods likely.

Assuming clear, dark skies, there is an increased chance of seeing the aurora tonight, 8^th-9^th June. Those in Scotland, northern England, and Northern Ireland have the best chance if the weather is favourable. Note however that with the reduced hours of darkness during the northern hemisphere summer, especially further North, the opportunity to view aurora may be limited by the lack of dark skies.

Glossary

BGS

The British Geological Survey is a geoscience research centre that is part of UK Research and Innovation (UKRI) and affiliated to the Natural Environment Research Council (NERC).

CME or Coronal Mass Ejection

The eruption of a portion of the outer atmosphere of the Sun into space, caused by rapid changes in its magnetic field. Often occurs along with a solar flare.

Solar Flare

Energy released by the explosive reorganisation of magnetic fields within the Sun's atmosphere.

Sunspot/Active Region

A region of intense magnetic field in the Sun's visible outer atmosphere often associated with flares and CMEs.
