MUNISING, MI — Pictured Rocks National Lakeshore got a stunning light show on Sunday, Sept. 14 as the sky lit up green, purple and red.
Park rangers snapped photos of the Aurora Borealis stunning along the Lake Superior and Munising Bay shoreline at Sand Point Beach. You can see the other colors captured on the park Facebook page.
The national lakeshore has 42 miles of Lake Superior shoreline and the luxury of limited light pollution, making for an optimal viewing experience.
From the beaches of the Upper Peninsula down to sunflower fields in Lapeer County in the thumb, the Northern Lights were showing off.
On Sunday night, the NOAA/NWS Space Weather Prediction Center confirmed a G3 geomagnetic storm.
The storm watch scale runs from G-1 (minor) to G-5 (extreme). The G scale measures intensity of solar activity and its effects on Earth’s magnetosphere, according to NOAA.
Strength and visibility is measured by the Kp index. The scale is used to indicate the severity of the global magnetic disturbances in near-Earth space, according to NOAA. Kp ratings are from zero to 9.
The view line for Monday, Sept. 15 cuts just below the U.P., meaning its less likely that the Lower Peninsula will get an encore show. The forecast for Monday night is a Kp of 3 and G-scale of 0.
