Residents in as many as 20 states may have the chance to witness the northern lights on Thursday night, with Michigan among the best viewing locations, according to the National Oceanic and Atmospheric Administration (NOAA).
The aurora borealis is expected to appear late on Thursday, November 6, and continue into the early hours of Friday, November 7, as reported by NOAA's Weather Prediction Center. Clear skies will improve visibility, and there may be another opportunity to see the lights on Friday night.
NOAA forecasts a moderate geomagnetic storm triggered by solar eruptions earlier in the week. These solar events sent charged particles toward Earth, interacting with its magnetic field and allowing the aurora to be visible farther south than usual.
In Michigan, the lights could be seen directly overhead as far south as Traverse City, Gaylord, and Alpena. Those farther south, including areas of northern Ohio and Indiana, may catch a view of the aurora low on the horizon.
“A G3 geomagnetic storm is expected to produce a Kp index of 7,” NOAA stated. “Kp is a standard measure of geomagnetic disturbances in near-Earth space, rated on a scale from 0 to 9.”
A Kp index of 5 or higher usually indicates that the northern lights are visible across much of Michigan.
NOAA predicts strong northern lights activity on Nov. 6–7 due to a moderate geomagnetic storm, offering a rare viewing chance across Michigan and neighboring states.
