Aurora visibility threshold for Marne La Vallee. At a geomagnetic latitude of 50.3°, the minimum Kp giving a realistic chance of visible auroras above Marne La Vallee 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 Marne La Vallee right now. Temperature +14.2°C, atmospheric pressure 758.6 mm Hg (1011.4 hPa), cloud cover 0%, humidity 48%, wind 10.2 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 Marne La Vallee page shows both indicators side by side. Weather data from Open-Meteo (CC BY).
