A minor solar storm is around according to the alert issued by the Space Weather Prediction Service.
The Sun is the source of solar wind – a stream of charged particles that can travel across the 150 million km that separate us from our star. These charged particles can interact with the Earth’s magnetic field and can spiral in towards the Earth’s surface at the magnetic poles. This can cause aurora, like the ones in the footage from Sweden on 14 March 2018.
Ireland is less likely to see aurora, because we are geomagnetically south – not only at a southerly latitude, but away from the magnetic north pole (which is currently in northern Canada). If you want to track the current space weather, check out spaceweather.com or the Space Weather Prediction Centre.
ESA have produced this lovely poster to show the various effects of space weather:
