More people will be able to see the dazzling display, with auroras visible in Scotland and the north of England and as far south as New York, Wisconsin and Washington states, according to United States and United Kingdom authorities.
Geomagnetic storms are large disturbances in the Earth’s magnetic field caused by changes in the solar wind and the structure of the interplanetary magnetic field. This latest storm was triggered on Saturday by a strong coronal mass ejection — a hugely energetic explosion of light, solar material and energy from the Sun.
The Northern Lights are driven primarily by solar winds — particles emitted from the sun that flow out through space and tear through Earth’s magnetosphere, creating a colorful light show.
Such space weather caused by the sun is important to understand, because, in addition to power grid ramifications, it can impact satellites, GPS, airlines, rockets and astronauts working in space.
In the UK, the Met Office said it would be possible to catch a glimpse of auroras on Tuesday night across most of Scotland and a “slight chance” further south, in the North of England and Northern Ireland. However, it cautioned that the weather was likely to be cloudy, making sightings unlikely.
The effect of geomagnetic storms can be felt for a number of days, according to the Met Office.
The weather forecasting service also said that minor geomagnetic storms may continue Tuesday, before a fast wind from a coronal hole may arrive, continuing a rather active period of geomagnetic activity.
