Geomagnetic storms in Akureyri today, 19 October 2026: Kp 5, G1 storm
The Kp index is planetary — in Akureyri it is the same as everywhere. What differs is whether the aurora reaches the city: Akureyri needs Kp 0.0.

In short
A geomagnetic storm is a disturbance of Earth's magnetic field by the solar wind. Its strength is measured by the planetary Kp index from 0 to 9: up to Kp 4 is quiet, Kp 5 is a minor storm (G1), Kp 7 is strong (G3), Kp 9 is extreme (G5). The index is the same for the whole planet, so “storms in London” and “storms in Edinburgh” are one and the same number; what differs is the latitude from which the storm is visible as aurora. CAMPLY shows solar wind from a satellite for the next hour, the Kp forecast for three days and the 27-day outlook.

FAQ
Frequently asked questions about geomagnetic storms
Will there be a geomagnetic storm today?
The forecast peak for today is Kp 5: that is a G1 storm. Kp 5 and above counts as a storm. This line refreshes every three hours.
Do storms differ between cities?
No. The Kp index is planetary — one number for every city. What differs is whether you'll see the aurora: Edinburgh needs Kp 3.9, London Kp 6.3.
How accurate is the forecast?
Solar wind measured by a satellite reaches Earth in about 40 minutes — that is the most reliable horizon. The three-day and 27-day forecasts are model-based and lose accuracy with range.
Do geomagnetic storms affect health?
There is no reliable scientific evidence of a direct effect on health. We show the geomagnetic data as it is, with no medical advice.
