Solar storm: UK on aurora alert as blast of plasma from Sun could trigger Northern Lights

These are expected to be possibly visible as low as Pennsylvania to Iowa to Oregon, in the US, as well as Northern Europe and the UK.

Auroras are billowing streams of light that appear near the planet’s poles when electrons collide with the upper layers of the atmosphere.

In the Northern Hemisphere, these are known as the Northern Lights or Aurora Borealis, and the Southern Lights (Aurora Australis) south of the equator.

According to astronomer and science journalist Will Gater, there is a possibility of Northern Lights being visible over parts of the UK tomorrow.
