* 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.

About magnetic storms in Usol'ye-Sibirskoye
Magnetic storm in Usol'ye-Sibirskoye today: planetary Kp = 0.0 (quiet). Over the last 7 days the maximum Kp above Usol'ye-Sibirskoye reached 5.3 (G1); storm days (G1+) this week: 2.
Usol'ye-Sibirskoye sits at geomagnetic latitude 43.4°. The nearest magnetic observatory continuously recording the field is Irkutsk (Patrony), 76 km away. Population 85,900.
Usol'ye-Sibirskoye sits at low latitudes (43.4°), 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 Usol'ye-Sibirskoye (43.4°, 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 Usol'ye-Sibirskoye 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 Usol'ye-Sibirskoye 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 Usol'ye-Sibirskoye. At a geomagnetic latitude of 43.4°, the minimum Kp giving a realistic chance of visible auroras above Usol'ye-Sibirskoye is about Kp ≥ 8. 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 Usol'ye-Sibirskoye right now. Temperature +18°C, atmospheric pressure 723.1 mm Hg (964.1 hPa), cloud cover 86%, humidity 52%, 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 Usol'ye-Sibirskoye page shows both indicators side by side. Weather data from Open-Meteo (CC BY).
Aurora viewing window for Usol'ye-Sibirskoye tonight. Sunset is at 01:13 local time, sunrise tomorrow at 11:02. Moon phase — waxing gibbous with 87% 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..
