About aurora viewing in Green Bay, WI

Green Bay, WI sits at roughly 44.5°N, placing it in the mid-latitude aurora visibility band. Aurora sightings require a strong geomagnetic storm (Kp ≥ 6–7). When conditions align, look low on the northern horizon away from city light.

Best viewing is typically 22:00–02:00 local time. Prioritize dark-sky sites north of the city, low humidity, minimal cloud cover, and a moon that is below the horizon or in a low-illumination phase.
