Kp is a planetary index — the same globally. Local impact depends on geomagnetic latitude: the higher it is, the more noticeable the storm.

▸About magnetic storms in Lanzhou
Magnetic storm in Lanzhou today: planetary Kp = 0.3 (G0). Over the last 7 days the maximum Kp above Lanzhou reached 4.7 (G0); storm days (G1+) this week: 0.
Lanzhou sits at geomagnetic latitude 26.7°. The nearest magnetic observatory continuously recording the field is Irkutsk (Patrony), 1803 km away. Population 3,000,000.
Magnetic storms and health of Lanzhou 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 Lanzhou 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 Lanzhou during the last 24 hours. Kp reached a maximum of 3.3 around 08:00 local time and dipped to 1.0. The planetary trend over the past 6 hours is falling — the magnetosphere near Lanzhou 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 Lanzhou. At a geomagnetic latitude of 26.7°, the minimum Kp giving a realistic chance of visible auroras above Lanzhou is about Kp ≥ 9. 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 Lanzhou right now. Temperature +15.4°C, atmospheric pressure 637.6 mm Hg (850 hPa), cloud cover 76%, humidity 27%, wind 16.3 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 Lanzhou page shows both indicators side by side. Weather data from Open-Meteo (CC BY).
Aurora viewing window for Lanzhou tonight. Sunset is at 00:52 local time, sunrise tomorrow at 11:10. 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..
