Northern Lights tonight in Kristiansand

Tonight in Kristiansand

Kristiansand sits at a geomagnetic latitude of 58.4° N, so the aurora usually needs a Kp index of about 3 or higher before it rises above the northern horizon. Tonight's NOAA forecast peaks at Kp 3 (quiet) during the dark hours, which is enough for Kristiansand.

The Moon is 100% 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 11% chance of aurora in the part of the sky visible from Kristiansand. OVATION is a short-range nowcast (30 to 90 minutes ahead), useful for deciding whether to step outside now.

3-day Kp forecast

1 of the next 3 days reach the Kp 3 that Kristiansand 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 Kristiansand needs Kp 3

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.

At 58.4° geomagnetic, Kristiansand needs about Kp 3 for aurora low on the horizon, Kp 5 or more for a display high in the sky. Stavanger, 161 km away, needs about Kp 2.
