High sensitivity (sub-auroral zone)
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.

About magnetic storms in Sestroretsk
Magnetic storm in Sestroretsk today: planetary Kp = 2.7 (quiet). Over the last 7 days the maximum Kp above Sestroretsk reached 5.7 (G1); storm days (G1+) this week: 2.
Sestroretsk sits at geomagnetic latitude 56.9°. The nearest magnetic observatory continuously recording the field is Saint Petersburg (Voeikovo), 44 km away. Population 37,248.
Sestroretsk lies in the sub-auroral zone (56.9°), 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 Sestroretsk (sub-auroral zone, 56.9°) 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 Sestroretsk during the last 24 hours. Kp reached a maximum of 4.0 around 12:00 local time and dipped to 1.0. The planetary trend over the past 6 hours is falling — the magnetosphere near Sestroretsk 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 Sestroretsk. At a geomagnetic latitude of 56.9°, the minimum Kp giving a realistic chance of visible auroras above Sestroretsk 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 Sestroretsk right now. Temperature +10.4°C, atmospheric pressure 744.4 mm Hg (992.4 hPa), cloud cover 100%, humidity 86%, wind 22.7 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 Sestroretsk page shows both indicators side by side. Weather data from Open-Meteo (CC BY).
Aurora viewing window for Sestroretsk tonight. Sunset is at 18:09 local time, sunrise tomorrow at 07:24. Moon phase — waning crescent with 2% 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..
