* Days marked with an asterisk do not have a direct NOAA forecast yet. If we have observations from 27 days ago, we use Bartels recurrence (the Sun rotates roughly every 27 days, so active regions often return with the same period). When no history is available, we substitute a baseline value typical for the current solar cycle 25 peak (Kp 3.0). Accuracy is lower than the direct three-day forecast.
How the score works
The composite score combines three signals: how strong the storm needs to be at your geomagnetic latitude, how bright the moon will be (a full moon hides faint auroras), and how cloudy the sky will be that night. A score of 70 or higher is excellent, 45 to 70 is good, below 20 means you probably will not see anything.

About magnetic storms in Saint-Quentin-en-Yvelines
Magnetic storm in Saint-Quentin-en-Yvelines today: planetary Kp = 1.3 (quiet). Over the last 7 days the maximum Kp above Saint-Quentin-en-Yvelines reached 5.0 (G1); storm days (G1+) this week: 2.
Saint-Quentin-en-Yvelines sits at geomagnetic latitude 50.4°. The nearest magnetic observatory continuously recording the field is Lviv, 1574 km away. Population 146,598.
Saint-Quentin-en-Yvelines is located at mid-latitudes (50.4°), where storm effects on the body are usually mild and noticeable mainly during severe G4 to G5 events. At Kp ≥ 6, some weather-sensitive people may report pressure swings, headaches or restless sleep; routine precautions like extra hydration, less caffeine and lighter physical load during the strongest events are usually enough.
For most technical systems in Saint-Quentin-en-Yvelines (50.4°, mid-latitudes), routine geomagnetic activity has little practical effect. Noticeable GPS, HF radio or grid issues are largely confined to severe G4 to G5 storms. Long-haul drivers, surveyors and HF operators in the region may want to check the forecast during the strongest events. Source: NOAA Space Weather Prediction Center, refreshed every 10 minutes.
Over Saint-Quentin-en-Yvelines during the last 24 hours. Kp reached a maximum of 5.0 around 20:00 local time and dipped to 3.0. The planetary trend over the past 6 hours is falling — the magnetosphere near Saint-Quentin-en-Yvelines is in the recovery phase. So far this month the planet has logged 2 days with a G1 or stronger geomagnetic storm.
Aurora visibility threshold for Saint-Quentin-en-Yvelines. At a geomagnetic latitude of 50.4°, the minimum Kp giving a realistic chance of visible auroras above Saint-Quentin-en-Yvelines is about Kp ≥ 6. The current equatorial Dst index is 0 nT — the magnetosphere is in a quiet phase. Dst complements Kp by showing how long and how deep a storm's main phase has been — useful context when checking whether auroras are likely tonight.
Weather and atmospheric pressure in Saint-Quentin-en-Yvelines right now. Temperature +16°C, atmospheric pressure 753.1 mm Hg (1004.1 hPa), cloud cover 100%, humidity 64%, wind 12.6 km/h. During G1+ geomagnetic storms, swings in atmospheric pressure tend to amplify symptoms for weather-sensitive people: those with hypertension often notice blood-pressure spikes, and readings below 1000 hPa combined with Kp ≥ 5 frequently bring headaches and fatigue. That is why the Saint-Quentin-en-Yvelines page shows both indicators side by side. Weather data from Open-Meteo (CC BY).
Aurora viewing window for Saint-Quentin-en-Yvelines tonight. Sunset is at 20:54 local time, sunrise tomorrow at 04:48. Moon phase — waning crescent with 7% disk illumination. Heavy cloud cover lowers the chance of seeing auroras even during a strong storm — it may be worth waiting for the next clear night..
