Northern Lights May Be Visible in 20 US States, Including Michigan
Millions of people across up to 20 U.S. states could witness the northern lights on Thursday night, November 6, weather permitting. Michigan residents, in particular, have a strong chance of seeing a vivid display of the aurora borealis.
Viewing Times and Locations
The National Oceanic and Atmospheric Administration (NOAA) reports that the aurora will be visible starting late Thursday night, November 6, extending into the early morning hours of Friday, November 7. There is also potential for sightings again on Friday night.
Geomagnetic Storm and Its Impact
The northern lights are fueled by a moderate geomagnetic storm triggered by recent solar eruptions that sent charged particles toward Earth's magnetic field. This event allows the lights to appear farther south than usual.
- In Michigan, the aurora may be visible overhead as far south as Traverse City, Gaylord, and Alpena.
- The northern horizon viewing line could extend down to northern Ohio and Indiana.
Geomagnetic Activity and Predictions
NOAA anticipates a G3 geomagnetic storm, a significant disturbance in Earth's magnetic environment. This will produce a Kp index of 7, which measures global magnetic activity on a scale from 0 to 9.
"An index of 5 or greater typically means the northern lights may be visible across Michigan," NOAA explained.
The Kp index of 7 indicates strong geomagnetic activity, increasing the chances of aurora visibility well into more southern locations than usual.
Summary
This geomagnetic storm offers a rare chance for many across the U.S. Midwest and beyond to experience the northern lights. Clear skies will be essential for the best views.
"The northern lights may be visible again Friday night," reports NOAA's Weather Prediction Center.
Residents and visitors in Michigan are encouraged to look to the northern horizon late Thursday night and early Friday morning for a spectacular natural show.
Author’s Summary
This week’s solar storm brings an excellent opportunity to see the northern lights across 20 states, with prime viewing in Michigan and areas farther south than usual.
