Minimum Kp shown for a realistic chance of seeing an aurora. The lower the number, the more noticeable storms are in the city.
FAQ about magnetic storms in Normandy
Are auroras visible in Normandy?+
Rarely. The geomagnetic latitude of Normandy (≈ 51.3°) is not high enough for regular auroras. They are possible only during strong storms Kp ≥ 6 (G3–G4), a few times a year.
How do magnetic storms affect residents of Normandy?+
At Kp ≥ 5 weather-sensitive people may experience blood pressure swings, headaches, sleep disturbances. Effects are moderate due to low geomagnetic latitude. However, strong G3+ storms can cause noticeable discomfort even here.
What Kp is needed to see an aurora in Normandy?+
By our estimate — Kp ≥ 6 (based on the regional mean of 51.3° geomagnetic latitude). The threshold is lower in the north of the region and higher in the south. For a specific city, open its page and check the «Aurora visibility threshold» section.
Where is the best place to watch auroras in Normandy?+
Best conditions are at the northernmost city in our database (Le Havre, 49.5° N). The further north, the higher the geomagnetic latitude and the more frequent the auroras. Also important: clear sky, no city light pollution, and observation around local midnight.
What is the nearest magnetic observatory?+
The nearest observatory is Lviv, at 1684 km from the centre of Normandy. It belongs to the INTERMAGNET network and records the geomagnetic field in real time.
About magnetic storms: Normandy
Magnetic storms in Normandy (France) today: planetary Kp = 3.0 (quiet). The database holds 3 cities in the region with live geomagnetic data and forecasts.
Pick a city from the list to see detailed information: local time, geomagnetic latitude, distance to the nearest magnetic observatory, 3-day Kp chart with forecast and aurora visibility chance. All cities in Normandy use the same planetary Kp, but the local impact is computed individually per coordinates.
How a magnetic storm may manifest in Normandy: at Kp ≥ 5, weather-sensitive people can have headaches, blood-pressure swings, sleep disruption. At Kp ≥ 7, GPS navigation and shortwave radio may glitch. At Kp ≥ 8 — power-grid issues. Data from NOAA SWPC, updated every 10 minutes.
Inside Normandy, geomagnetic latitude varies from 51.2° to 51.4°, with a mean of 51.3°. The northernmost city, Le Havre, gets aurora visibility opportunities first when Kp climbs; the 0.2° south-to-north spread is enough to put neighbouring cities into very different storm-response groups.
The nearest magnetic observatory tracking conditions over Normandy is Lviv. Combined with the planetary Kp index from NOAA SWPC, this station gives the closest reference point for how the local magnetic field behaves during storms in this part of France.
