Magnetic storms in Erfurt

Magnetic storm in Erfurt today: planetary Kp = 0.3 (G0). Over the last 7 days the maximum Kp above Erfurt reached 4.7 (G0); storm days (G1+) this week: 0.

Erfurt sits at geomagnetic latitude 51.1°. The nearest magnetic observatory continuously recording the field is Lviv, 907 km away. Population 213,692.

Magnetic storms and health of Erfurt residents: at Kp ≥ 5 weather-sensitive people may experience pressure swings, headaches, sleep issues. Especially pensioners and people with hypertension should watch the forecast. During a storm — hydrate more, avoid alcohol and strong coffee, avoid intense physical load.

Technical consequences for Erfurt at G3+: GPS, HF radio and precise positioning systems may glitch. Drivers on long routes should watch the forecast for the next 24–72 hours. Data source: NOAA Space Weather Prediction Center, refreshed every 10 minutes.

Over Erfurt during the last 24 hours. Kp reached a maximum of 3.3 around 02:00 local time and dipped to 1.0. The planetary trend over the past 6 hours is falling — the magnetosphere near Erfurt is in the recovery phase. So far this month the planet has logged no G1+ storm days with a G1 or stronger geomagnetic storm.

Aurora visibility threshold for Erfurt. At a geomagnetic latitude of 51.1°, the minimum Kp giving a realistic chance of visible auroras above Erfurt 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 Erfurt right now. Temperature +9°C, atmospheric pressure 743.2 mm Hg (990.9 hPa), cloud cover 100%, humidity 84%, wind 3.4 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 Erfurt page shows both indicators side by side. Weather data from Open-Meteo (CC BY).

Aurora viewing window for Erfurt tonight. Sunset is at 19:40 local time, sunrise tomorrow at 04:45. Moon phase — waning gibbous with 98% 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..
