A pair of powerful solar storms is heading towards Earth and is expected to bring the northern lights may be visible across parts of the UK this week.
The two coronal mass ejections (CMEs) erupted from the Sun within hours of each other over the weekend. Forecasters say the second, larger eruption is likely to catch up with and absorb the first before reaching Earth, creating what scientists call a rare “cannibal CME.”
This phenomenon is forecast to trigger striking aurora displays in both hemispheres, with the UK Met Office predicting that much of the country could catch a glimpse of the spectacle between Monday and Wednesday nights. The US National Oceanic and Atmospheric Administration (NOAA) has also warned that auroras could extend unusually far south across North America, reaching states such as Michigan, Montana and New York.
The Weather Agency, said:
“A fast-moving coronal mass ejection (CME) that departed the Sun late on 30 August is forecast to arrive at Earth late on 1 September or early on 2 September.
Following its arrival, a significant enhancement of the auroral oval is likely, potentially continuing into 3 September.
At peak activity, and where skies are sufficiently dark and clear, aurora may be visible as far south as East Anglia, the Midlands, Wales, and other regions at similar geomagnetic latitudes – without the need for photographic equipment.”
In the Southern Hemisphere, sky watchers in southern Australia and New Zealand are expected to witness the aurora australis during peak activity.
Auroras form when solar particles from a CME collide with Earth’s magnetic field and atmosphere, releasing energy that lights up the sky with vivid colours. For the best chance of seeing the display, experts recommend heading to areas with minimal light pollution and clear skies.
According to the Met Office, the early hours of Tuesday, 2 September, are expected to provide the most favourable conditions for northern lights viewing in the UK.
