Following a recent alert for possible Northern Lights activity across Wales, the Sun has produced a further Earth-facing solar flare which could well light up Welsh skies this weekend.

A powerful so-called X1-class solar flare, the Sun’s most powerful kind of flare, was generated on Thursday October 28th, sending out a substantial cloud of charged particles in the Earth’s direction that looks set to arrive during Saturday and Sunday. 

The particles, travelling at 2.5 million miles per hour, will collide with the Earth’s upper atmosphere, causing it to literally fluoresce in a range of colours.

This is the Sun’s second most powerful eruption of 2021 and comes at the start of the Sun’s newest solar-cycle, an 11 year cycle which sees activity on the Sun’s surface rise and fall.

To view the possible display of the Aurora Borealis, also known as Ffagl yr Arth (the bear's firebrand), find yourself a dark but safe observing position, away from as much light-pollution as possible, and look above the northern horizon.
