Just over a dozen states in the northern U.S. might have an opportunity to see the aurora borealis on Friday, following the influence of a cooler, less dense spot on the sun’s surface, according to the National Oceanic and Atmospheric Administration.
A cooler, less dense area on the sun’s surface will likely disrupt Earth’s magnetic field, forecasters said.

Key Facts
NOAA forecast a Kp index of five on a scale of nine, suggesting the aurora borealis will be brighter and “quite pleasing to look at” for those in the right areas.
An uptick in auroral activity is expected on Friday, with “minor” geomagnetic storms forecast for Friday night, early Saturday morning and Sunday, according to NOAA, which noted the storms were because of “anticipated influence” from a coronal hole on the sun’s surface.
Similar auroral activity is forecast for Saturday and Sunday, with a maximum Kp index of four for either night.
Where Will The Northern Lights Be Visible?
A higher likelihood of viewing the aurora borealis is projected across northern Canada and Alaska, while a lower chance is forecast for parts of Washington, Idaho, Wyoming, North Dakota, Minnesota, Wisconsin and Michigan. A lesser, yet still possible likelihood is expected in parts of Montana, South Dakota, Iowa, New York, New Hampshire, Vermont and Maine. (See view line below).
What’s The Best Way To See The Northern Lights?
The northern lights are best seen between 10 p.m. and 2 a.m. local time, according to NOAA, which recommends traveling as far north as possible to a high, north-facing vantage point away from light pollution.
What’s The Best Way To Photograph The Northern Lights?
If using a regular camera, photography experts recommend using an F-stop or aperture of four or less and a focus set to the furthest possible setting. iPhone users are recommended to enable night mode, while Android users should take photos in Pro mode. A tripod is suggested to stabilize the image.
