Northern Lights to Stun in UK Skies Tonight - Best Time to See Them

Three coronal mass ejections may trigger a severe to extreme geomagnetic storm with possible radio, GPS disruption, and local power impacts, says the Met Office.

  • The Met Office's space weather team put a G4–G5 geomagnetic storm watch in place on Wednesday, warning of widespread Northern Lights expected that night across the UK.
  • Scientists say two CMEs arrived on Tuesday night and one set for Wednesday night from the Sun, disturbing Earth's magnetosphere.
  • Scientists at the Met Office explain that charged particles from CMEs excite atmospheric molecules, producing light and potentially disrupting radio and GPS systems, with extreme cases damaging transformers and localised power infrastructure.
  • There is a chance of sightings further south across England and Wales, though cloud cover is expected to inhibit ideal viewing for many, so pick dark viewing sites away from street lights.
  • Met Office experts say UK impacts should generally be limited despite heightened activity, but geomagnetic storms increase the chance of northern lights potentially spanning the country and similar latitudes worldwide.
