As the sun continues the tumultuous peak of its 11-year cycle, more instances of aurora borealis have been expected. The most recent instance was earlier in August when auroras lit up the skies in 18 states. It seems the Earth is in for another battering of solar material as another aurora has been forecast for Monday night, and it should be a pretty decent one for states in the northern US.
According to NOAA, the Earth will experience a geomagnetic storm with a Kp 5 rating. For the uninitiated, the K-index is a measure of how strong geomagnetic storms are and a Kp 5 rating is designated as a «moderate» storm by NOAA. In general, the stronger the geomagnetic storm, the further south an aurora appears, and a Kp 5 will almost assuredly drag the northern lights into the US.
This week’s geomagnetic storm comes to us courtesy of the sun. Per SpaceWeatherLive, there were a number of solar flares ejected from the sun over the last several days, a pattern of increased solar activity that also caused the aurora on Aug. 8.
Where will the aurora be visible?
The states that can be expected to see it include Washington, the northern tip of Idaho, Montana, North and South Dakota, Wisconsin, Minnesota and the northern horn of Michigan. If it’s dark enough and people face north, it may also be visible in Wyoming, Iowa, New York, Vermont, New Hampshire and Maine. Of course, the best view will be in Alaska, where the whole state should be able to see the most intense part of the aurora.
NOAA says the storm will peak at around 0300 to 0900 UTC, which translates to 11 p.m. through 5 a.m. ET (8 p.m. to 2 a.m. PT).
Tips to see the aurora
If you live in one of the aforementioned states, your best bet is to get somewhere elevated and away from city or suburban light pollution, and then simply point yourself north. Photographers looking to catch a glimpse will want to use long exposure times to give the camera ample time to take in as much aurora light as possible.
If you plan on taking a trip out to the sticks to see it, keep an eye out for shooting stars at the tail end of Perseids meteor shower and you may be able to spot some plants in the last planet parade of 2025.
