Northern Lights tonight in Genoa

Tonight in Genoa

Genoa sits at a geomagnetic latitude of 45.0° N, so the aurora is only seen here in extreme Kp 9 storms, and then mostly by cameras. Tonight's NOAA forecast peaks at Kp 1.7 (quiet) during the dark hours, far below that.

Open-Meteo expects about 29% cloud cover on average between 7 pm and 6 am local time, with 6 of 11 dark hours mostly clear (30% cloud or less).

The Moon is 99% illuminated (full moon), bright enough to wash out a faint aurora, so only a stronger display will stand out. For the best view look north, low on the horizon, from somewhere away from street lights.

Right now NOAA's OVATION model gives up to 0% chance of aurora in the part of the sky visible from Genoa. OVATION is a short-range nowcast (30 to 90 minutes ahead), useful for deciding whether to step outside now.

3-day Kp forecast

None of the next 3 days reaches the Kp 9 that Genoa needs. Kp is a global 0–9 index of geomagnetic activity, issued in 3-hour blocks (UTC); NOAA forecasts beyond 24 hours are uncertain, because storms are triggered by solar eruptions that take 1–3 days to arrive.

Why Genoa needs Kp 9

The aurora forms in an oval around the geomagnetic pole, which sits in the Canadian Arctic (about 80.8° N, 72.8° W), not at the geographic pole. That is why the Kp a city needs depends on its geomagnetic rather than its geographic latitude. At Kp 0 the oval's edge is near 66° geomagnetic; each step of Kp pushes it roughly 2° toward the equator.

Genoa is at 45.0° geomagnetic, far enough from the pole that only extreme (Kp 9, G5) storms like May 2024 bring the aurora into view, and then mostly to cameras.
