Some stargazers captured the Aurora
Borealis over Northern Michigan Thursday night. However, clouds obscured much of the display for West Michigan.
The probability of seeing the Aurora Borealis is based on the Kp index, which measures global geomagnetic storms. As the Kp number rises, so does the likelihood of seeing the Aurora Borealis.
The Kp number must reach at least a 7 to see the colorful display in lower Michigan. The National Oceanic and Atmospheric Administration said as of Friday afternoon, the Kp index was at 8. Storm Team 8 also expects the skies over West Michigan to be clear.
