The lights have been seen over Northumberland on Wednesday evening, and the exercise is anticipated to start out subsiding from Saturday.
Professor Don Pollacco, division of physics on the College of Warwick, mentioned it might be tough to foretell precisely the place the Northern Lights could be seen.

“It’s really a bit like iron filings and the sphere of a bar magnetic.
“The photo voltaic wind incorporates extra particles when there are solar spots, as these are areas on the solar’s floor the place the magnetic subject is interacting with the plasma within the Solar, and the particles might be launched.
“As soon as the particles are channelled into the Earth’s environment they work together with molecules and have distinctive colors (eg oxygen molecules produce inexperienced gentle, nitrogen crimson gentle and so on) and patterns resembling gentle emissions that seem like curtains or spotlights.
“These shapes over change shortly over timescales of minutes/seconds.”
