Where to look in Milwaukee
At Milwaukee's latitude the aurora appears low on the northern horizon during geomagnetic storms (Kp 8 or more), often as a green or reddish glow rather than dancing curtains overhead. Drive away from the city lights to a place with an open view to the north – a lake shore, a field or a hilltop – and use a phone camera in night mode, which picks up color the eye misses.
A bright moon and haze both wash out a faint display; check the hourly cloud cover above and look again later in the evening, when NOAA's short-term OVATION model gives a better picture of the next hour.
Northern lights in Milwaukee
Can I see the northern lights in Milwaukee, Wisconsin tonight?
Unlikely: unlikely tonight. Milwaukee needs about Kp 7.1; the forecast for its dark hours tonight is up to Kp 1.7, with 0 % cloud cover on average.
What Kp is needed to see the aurora in Milwaukee, Wisconsin?
Milwaukee: about Kp 7.1 (geomagnetic latitude 51.9°).
What is the best time to see the aurora?
Usually between about 10 PM and 2 AM local time, when your part of the Earth faces the night-side of the auroral oval – but during a strong storm it can appear as soon as it is dark. Give your eyes 15–20 minutes away from screens and lights.
Why can my phone see the aurora when I can't?
A phone camera's long exposure collects far more light than the eye and sees color better in the dark. At lower latitudes a faint aurora often looks grey or white to the eye and green or pink on a 3-second phone shot – try night mode pointed north.
How accurate is the forecast?
Kp forecasts a day or more ahead come from observations of the Sun and are uncertain by a step or two; the timing of a storm's arrival can be off by many hours. The OVATION model is good for the next 30–90 minutes. Check the page again in the evening.
