The sun has unleashed the most powerful solar flare since 2017, just days after it spat out another monster explosion. Both outbursts have launched solar storms that will likely hit Earth this weekend and trigger vibrant aurora displays.

This alert comes as two coronal mass ejections (CMEs) are expected to make their way to Earth this weekend. A geomagnetic storm occurs when solar wind — a stream of charged particles from the Sun — collides with Earth’s magnetic field.

A health expert has issued a warning to people who could be affected by the incoming solar storm - and explained the steps you should take to lessen the impact
