Northern Lights Visible in 20 US States, Including Michigan
Up to 20 states could witness the northern lights on Thursday night, weather permitting. Michigan residents have a good chance to see a strong display on Thursday, November 6, as the National Oceanic and Atmospheric Administration (NOAA) reports.
The aurora is expected to be visible from late Thursday night into the early morning of Friday, November 7. It may also appear again on Friday night.
Where to See the Northern Lights in Michigan
The aurora could be overhead in areas as far south as Traverse City, Gaylord, and Alpena. The northern lights may also be visible along the horizon as far south as northern Ohio and Indiana.
What Causes This Display?
NOAA attributes this event to a moderate geomagnetic storm caused by solar eruptions earlier in the week. Charged particles from the sun interacted with Earth’s magnetic field, allowing the lights to be seen farther south than usual.
Geomagnetic Storm Details
- A G3 geomagnetic storm, a global disturbance of Earth's magnetic field, is expected.
- It will produce a Kp index of 7, where Kp measures the severity of magnetic disturbances.
- Kp ratings range from 0 to 9; values of 5 or greater typically indicate visible northern lights in Michigan.
NOAA explained, “A Kp index of 7 signifies a strong magnetic disturbance, increasing the chances to observe the aurora even at lower latitudes.”
This week’s northern lights offer a rare opportunity for many in the U.S. to enjoy this spectacular natural phenomenon.
Summary: Michigan and up to 19 other states may witness the northern lights due to a strong geomagnetic storm, with the best viewing on the nights of November 6 and 7.
