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.

* Days marked with an asterisk do not have a direct NOAA forecast yet. If we have observations from 27 days ago, we use Bartels recurrence (the Sun rotates roughly every 27 days, so active regions often return with the same period). When no history is available, we substitute a baseline value typical for the current solar cycle 25 peak (Kp 3.0). Accuracy is lower than the direct three-day forecast.
How the score works
The composite score combines three signals: how strong the storm needs to be at your geomagnetic latitude, how bright the moon will be (a full moon hides faint auroras), and how cloudy the sky will be that night. A score of 70 or higher is excellent, 45 to 70 is good, below 20 means you probably will not see anything.
Magnetic storms in Putuo over the last 30 days

About magnetic storms in Putuo
Magnetic storm in Putuo today: planetary Kp = 0.0 (quiet). Over the last 7 days the maximum Kp above Putuo reached 5.3 (G1); storm days (G1+) this week: 2.
Putuo sits at geomagnetic latitude 22.2°. The nearest magnetic observatory continuously recording the field is Irkutsk (Patrony), 2712 km away. Population 1,239,100.
Putuo sits at low latitudes (22.2°), where geomagnetic storms have very limited impact on health. Scientific links between Kp and well-being are weak this far from the auroral oval, and only the strongest Carrington-class events would be expected to affect sensitive groups. Standard healthy habits, good sleep, hydration and moderate activity, remain the most reliable advice.
Technical systems in Putuo (22.2°, low latitudes) are well shielded from geomagnetic disturbances. Even extreme storms rarely cause meaningful GPS, radio or power-grid problems at this latitude, so routine activity, navigation and communications can be considered safe. For reference and historical events, data come from the NOAA Space Weather Prediction Center, updated every 10 minutes.
Over Putuo during the last 24 hours. Kp reached a maximum of 2.3 around 08:00 local time and dipped to 0.7. The planetary trend over the past 6 hours is falling — the magnetosphere near Putuo is in the recovery phase. So far this month the planet has logged 2 days with a G1 or stronger geomagnetic storm.
Aurora visibility threshold for Putuo. At a geomagnetic latitude of 22.2°, the minimum Kp giving a realistic chance of visible auroras above Putuo 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 Putuo right now. Temperature +31.7°C, atmospheric pressure 755.3 mm Hg (1007 hPa), cloud cover 41%, humidity 62%, wind 16.2 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 Putuo page shows both indicators side by side. Weather data from Open-Meteo (CC BY).
Aurora viewing window for Putuo tonight. Sunset is at 23:28 local time, sunrise tomorrow at 10:25. Moon phase — waxing gibbous with 85% 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..
