The NOAA Space Prediction Center forecasts possible aurora sightings for Michiganders over the next three nights, extending as far south as the upper Midwest. A minor (G1) to moderate (G2) geomagnetic storm is expected, with higher chances on Tuesday and Thursday nights. Auroras, caused by solar eruptions, may be visible along the northern horizon, especially in northern Michigan. The Kp value is forecasted to range from 5 to 6, indicating visibility in the northern U.S. The best viewing times are at night, away from city lights, typically around 10 p.m.
