Rare geomagnetic storms have led to stunning displays of northern lights over the weekend, with the possibility of more to come on Sunday night. The strong auroras have been caused by very fast-moving coronal mass ejections hitting Earth’s magnetic field. This has resulted in auroras visible as far south as Florida, which is only possible during a G5 level geomagnetic storm, the highest level on the scale.
These strong geomagnetic storms, which reached G5 levels on Friday and Saturday, have not been seen since 2005. There is a possibility of more storms of G4 or greater strength on Sunday, with a significant chance of seeing the northern lights in areas shaded in red on the forecast map. However, even areas not shaded may still get a glimpse of the aurora.
The heightened solar activity causing these storms is due to Solar Cycle 25, which was expected to peak this year. While the spectacle of the northern lights is a sight to behold, it also comes with potential impacts on power grids and other infrastructure. Despite this, no serious problems have been reported with this storm.
For those unable to see the northern lights in person, pointing a phone camera towards the night sky may capture a surprising glimpse of the aurora. The solar activity is predicted to continue this week, meaning that more chances to witness the northern lights may be in store for skywatchers.
