Tonight in Koblenz
Koblenz sits at a geomagnetic latitude of 51.0° N, so the aurora usually needs a Kp index of about 7 or higher before it rises above the northern horizon. Tonight's NOAA forecast peaks at Kp 1.7 (quiet) during the dark hours, 5.3 short of what Koblenz needs.
Open-Meteo expects about 92% cloud cover on average between 7 pm and 7 am local time, with 1 of 12 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 Koblenz. 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 7 that Koblenz 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.
| Day (UTC) | Max Kp | Level | Enough for Koblenz? |
|---|---|---|---|
| 2026-10-26 | 1.7 | quiet | No |
| 2026-10-27 | 1.7 | quiet | No |
| 2026-10-28 | 1.7 | quiet | No |
Why Koblenz needs Kp 7
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 51.0° geomagnetic, Koblenz needs about Kp 7 for aurora low on the horizon, Kp 9 or more for a display high in the sky. Bonn, 54 km away, needs about Kp 6.
