Parts of the northern-most U.S. will have yet another chance to see the Northern Lights this weekend as increased geomagnetic activity continues to provide observers with decent views of the atmospheric phenomenon.

Saturday’s aurora borealis forecast predicts a KP index of five, meaning forecasters expect the aurora to become brighter and provide a fair view for observers in the right areas, according to the National Oceanic and Atmospheric Administration.
NOAA’s space weather forecast for the weekend predicts moderate to high solar activity until Sunday at least, and notes a watch is in effect for a G1 storm—a minor geomagnetic storm capable of producing aurora visibility in northern states.
Saturday’s aurora forecast is more favorable than Sunday’s for those looking to get a glimpse at the Northern Lights, as the viewing line reaches slightly farther south into northern states.

Northern parts of states such as Washington, Idaho, Montana and Minnesota are above the viewing line (see map below) and have a low chance at seeing the lights. Most of North Dakota will also have a varying likelihood of an aurora borealis sighting.

The window between 10 p.m. and 2 a.m. is the sweet spot for those looking to catch a glimpse at the Northern Lights, with areas free of cloud cover and minimal light pollution most suitable for viewing.
Those looking to snap photos of the phenomenon with their smartphones should use night mode and a slow shutter speed if possible.
Increased solar activity impacting the northern U.S. and Canada has persisted since July, giving aurora borealis seekers multiple opportunities to catch the lights. Earlier this week, the Northern Lights and the Perseid meteor shower were seen in places such as New York, Poland, Spain and England. The jump in aurora borealis visibility is part of a larger stretch of solar activity experienced throughout 2024 and expected to increase as the sun approaches the peak of an 11-year solar cycle. NOAA has forecasted a 2025 peak of up to 115 sun spots, which are the source of geomagnetic storms before they produce auroras.
