Doncaster stargazers are being reminded they could catch some of the best Northern Lights displays in decades this weekend.
NASA has said three X-class flares have erupted from a sunspot that has now grown to 125,000 km wide since Sunday, October 18.
Solar flares are bursts of radiation emitted by the sun and are rated A, B, C, M, and X according to intensity, with X-class flares being the most powerful.
Alistair McLean, managing director of The Aurora Zone, said: “This sunspot is now 125,000 km wide, that’s about the size of Jupiter and ten times wider than Earth.
“It’s the largest of this Solar Cycle and appears to back up scientific research that suggests that major solar events happen in the early declining phase of Solar Maximum.”
“September and October have yielded some of the best and most frequent Auroral displays across the Arctic Circle we have seen in many a year, and it just keeps getting better and better. This winter really is proving to be a fantastic time to go to in search of the Northern Lights.”
