Northern Lights Could Appear This Week After Met Office Update
The Met Office said the solar blast may graze Earth and trigger minor geomagnetic storms that could brighten aurora displays across Britain and the northern United States.
Around May 13, the Met Office reports a coronal mass ejection could graze Earth, potentially triggering northern lights displays across the UK following a massive plasma expulsion from the Sun on May 10.
Bursting from sunspot region AR4436 at 9:39 a.m. EDT on May 10, the M5.7 eruption produced a Type II radio sweep traveling at 650 km/s, confirming a CME had launched from the Sun's surface.
Potential G1 geomagnetic storm conditions could result from the glancing blow, according to NOAA, with sky watchers in Scotland, northern England, and the northern United States potentially seeing the aurora if skies remain clear.
Radio communications across the Atlantic Ocean were disrupted on Sunday by the flare, which the Space Weather Prediction Center classified as an R2 moderate blackout affecting transatlantic pilots and mariners.
As AR4436 and nearby sunspot region AR4432 rotate into Earth's 'strike zone,' experts maintain a high probability of additional M-class or X-class eruptions over the coming days, increasing aurora display chances.
