Northern Lights Visible in Up to 20 US States Including Michigan
Residents in Michigan and other states may witness a strong display of the northern lights on Thursday night, November 6, weather permitting, according to the National Oceanic and Atmospheric Administration (NOAA).
When and Where to See the Aurora
The aurora borealis will be visible starting late Thursday night and continuing into the early morning of Friday, November 7. The lights may also be seen again on Friday night.
Due to a moderate geomagnetic storm caused by recent solar eruptions, the northern lights could appear farther south than usual.
Viewing Areas in Michigan
- The aurora could be directly overhead as far south as Traverse City, Gaylord, and Alpena.
- The northern horizon where the lights may be visible extends as far south as northern Ohio and Indiana.
Geomagnetic Storm Details
NOAA forecasts a G3 geomagnetic storm, a significant global disturbance of Earth's magnetic field, producing a Kp index of 7.
"Kp is an index used to indicate the severity of the global magnetic disturbances in near-Earth space," NOAA explained.
A Kp index rising from 0 to 9 signals storm intensity, with a rating of 5 or higher usually allowing northern lights to be visible across Michigan.
Summary
This week's geomagnetic activity offers a rare chance for many residents in mid-latitude states to observe the northern lights at unusually southern locations.
"States could have the opportunity to see the northern lights Thursday night," NOAA said.
An evening of aurora viewing is expected, especially if skies remain clear during the forecasted period.
Author’s Note
The approaching geomagnetic storm may provide a spectacular northern lights show visible across a broad swath of the US, including much of Michigan and neighboring states.
