Despite high expectations following Friday night’s spectacular Northern Lights display, geomagnetic activity remained high throughout Saturday but unfortunately not when the sky was dark enough to see it. The activity weakened from the extreme “G5” category to a severe “G3”, but there was still hope that the aurora would be visible across the UK. However, as darkness fell, geomagnetic levels fell below the threshold, leaving many disappointed at seeing nothing. Activity picked up again after midnight, but it was too late for most people.
The recent solar activity, with a large sunspot directed towards Earth, has resulted in numerous Coronal Mass Ejections (CME) that are like volcanoes sending charged particles into space. When directed towards Earth, these charged particles create the aurora. The strength and speeds of the CMEs can vary and they can sometimes combine to become more powerful just as they hit Earth.
Forecasters at NOAA and the Met Office Space Weather Centre are predicting the arrival of another strong CME on Sunday and into Monday, with geomagnetic activity expected to be strong to severe (G4) and a chance of an increase to extreme (G5). This means there is another opportunity to see the Northern Lights anywhere in the UK, but unfortunately, there will be more cloud and thundery showers across Scotland into northern England and parts of the Midlands, which may obstruct any chance of seeing the aurora.
Although there is no guarantee of a sighting, it is worth keeping an eye on the forecast for Sunday night to give yourself the best chance. Remember, the aurora can be influenced by several factors, including cloud cover and light pollution, so try to find a dark area with little light pollution for the best possible viewing. Fingers crossed for a glimpse of the stunning Northern Lights!
In conclusion, after disappointing sightings on Saturday, it is predicted that the geomagnetic activity associated with the aurora will remain strong to severe and possibly even increase to extreme levels. If you’re keen on experiencing the spectacle, it’s important to keep an eye on the weather forecast and try to avoid areas with light pollution. Here’s hoping we’ll be treated to another spectacular display of the Northern Lights
