Low sensitivity (low latitudes)
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 Sanya
Magnetic storm in Sanya today: planetary Kp = 1.0 (G0). Over the last 7 days the maximum Kp above Sanya reached 4.7 (G0); storm days (G1+) this week: 0.
Sanya sits at geomagnetic latitude 8.9°. The nearest magnetic observatory continuously recording the field is Irkutsk (Patrony), 3808 km away. Population 1,031,396.
Magnetic storms and health of Sanya 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 Sanya 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 Sanya 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 Sanya 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 Sanya. At a geomagnetic latitude of 8.9°, the minimum Kp giving a realistic chance of visible auroras above Sanya 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 Sanya right now. Temperature +30.1°C, atmospheric pressure 755.8 mm Hg (1007.7 hPa), cloud cover 5%, humidity 68%, wind 9.5 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 Sanya page shows both indicators side by side. Weather data from Open-Meteo (CC BY).
Aurora viewing window for Sanya tonight. Sunset is at 00:03 local time, sunrise tomorrow at 11:13. Moon phase — waning gibbous with 98% disk illumination. The Moon is close to full tonight, so moonlight will be strong and faint auroras will be harder to spot — wait for Kp ≥ 6 or pick a darker site..
