Solar storms could bring faint but visible auroras to the Northern Hemisphere from late Thursday into early Friday morning, but experts say they do not expect major disruptions to power grids or communications.

According to current space weather forecasts, people in Canada and northern U.S. states such as Alaska, Washington, Montana, North Dakota and Minnesota may see dim, colored images.

If moderate solar storms intensify as night approaches, people as far south as Illinois and New York could see the phenomenon.

For that to happen, “all the stars have to align,” said Erica Grow Say, a spokeswoman for the U.S. National Oceanic and Atmospheric Administration.

Wait for the sky to darken to see the show. Then head outside, ideally away from the bright lights of the city. Taking photos with a smartphone camera can also reveal hints of the aurora borealis that aren’t visible to the naked eye.

The sun’s magnetic field is at the peak of its 11-year cycle, causing storms and auroras to occur more frequently. Unusually strong solar storms in May caused bright auroras in the Northern Hemisphere.

Today’s storms are expected to be less severe, but could cause short-term disruptions to sensitive GPS equipment that farmers use to harvest crops, Grow Cei said.
