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.

The effects are expected to continue Tuesday and Wednesday, according to the UK's Met Office, which said there could be a "rather active period of geomagnetic activity."

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.

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.

The National Oceanic and Atmospheric Administration's Space Weather Prediction Center noted that the storm's impact would be felt above 55 degrees latitude, and it was possible that power grid fluctuations could occur. It said minor impact on satellite operations possible.
