Why Senja needs the Kp it does
Magnetic latitude, not map latitude
Most forecasts rank a place by its geographic latitude. But the Aurora follows Earth's magnetic field, and the two don't line up. Senja sits at 69.3°N on the map, yet its magnetic latitude is about 66.3°, placing it right under the auroral oval.
That gap is exactly why generic tools mis-rate locations. We calibrate to magnetic latitude, which is why our minimum Kp here is 0.1.
| Kp 1 | Faint glow low on the horizon. You're here |
| Kp 3 | Bright arcs: movement, colour to the eye |
| Kp 5 | Storm: fills the sky, curtains overhead |
| Kp 7+ | Rare, dramatic; visible far to the south |
