Magnetic storms in Bayan Nur

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

Bayan Nur sits at geomagnetic latitude 31.4°. The nearest magnetic observatory continuously recording the field is Irkutsk (Patrony), 1301 km away. Population 1,760,000.

Magnetic storms and health of Bayan Nur 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 Bayan Nur 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 Bayan Nur 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 Bayan Nur 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 Bayan Nur. At a geomagnetic latitude of 31.4°, the minimum Kp giving a realistic chance of visible auroras above Bayan Nur 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 Bayan Nur right now. Temperature +23.5°C, atmospheric pressure 671.8 mm Hg (895.6 hPa), cloud cover 72%, humidity 11%, wind 20.4 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 Bayan Nur page shows both indicators side by side. Weather data from Open-Meteo (CC BY).

Aurora viewing window for Bayan Nur tonight. Sunset is at 00:48 local time, sunrise tomorrow at 10:46. 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..
