* 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 Udachny
Magnetic storm in Udachny today: planetary Kp = 1.3 (quiet). Over the last 7 days the maximum Kp above Udachny reached 5.3 (G1); storm days (G1+) this week: 2.
Udachny sits at geomagnetic latitude 57.1°. The nearest magnetic observatory continuously recording the field is Yakutsk, 966 km away. Population 15,266.
Udachny lies in the sub-auroral zone (57.1°), where storms are felt several times per year. At G3 and stronger, weather-sensitive residents may experience blood-pressure changes, headaches and sleep issues; pensioners and people with hypertension should watch the forecast. During a storm, drink more water, avoid alcohol and strong coffee, and reduce intense physical exertion.
Technical consequences for Udachny (sub-auroral zone, 57.1°) appear from G4 upward: GPS and HF radio may degrade, precise positioning can drift, and northern power grids in the region carry a measurable GIC risk during the strongest events. Drivers on long routes should track the forecast for the next 24 to 72 hours. Source: NOAA Space Weather Prediction Center, updated every 10 minutes.
Over Udachny during the last 24 hours. Kp reached a maximum of 2.3 around 09:00 local time and dipped to 0.7. The planetary trend over the past 6 hours is rising — conditions near Udachny may intensify further. So far this month the planet has logged 2 days with a G1 or stronger geomagnetic storm.
Aurora visibility threshold for Udachny. At a geomagnetic latitude of 57.1°, the minimum Kp giving a realistic chance of visible auroras above Udachny is about Kp ≥ 5. 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 Udachny right now. Temperature +7.8°C, atmospheric pressure 737.2 mm Hg (982.9 hPa), cloud cover 53%, humidity 84%, wind 4.8 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 Udachny page shows both indicators side by side. Weather data from Open-Meteo (CC BY).
Aurora viewing window for Udachny tonight. Sunset is at 03:40 local time, sunrise tomorrow at 11:25. Moon phase — waxing gibbous with 84% 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..
