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.

About magnetic storms in Poronaysk
Magnetic storm in Poronaysk today: planetary Kp = 1.7 (quiet). Over the last 7 days the maximum Kp above Poronaysk reached 6.3 (G2); storm days (G1+) this week: 2.
Poronaysk sits at geomagnetic latitude 41.4°. The nearest magnetic observatory continuously recording the field is Paratunka (Kamchatka), 1135 km away. Population 16,677.
Poronaysk sits at low latitudes (41.4°), 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 Poronaysk (41.4°, 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 Poronaysk during the last 24 hours. Kp reached a maximum of 5.0 around 05:00 local time and dipped to 2.3. The planetary trend over the past 6 hours is steady — no sharp changes near Poronaysk right now. So far this month the planet has logged 2 days with a G1 or stronger geomagnetic storm.
Aurora visibility threshold for Poronaysk. At a geomagnetic latitude of 41.4°, the minimum Kp giving a realistic chance of visible auroras above Poronaysk 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 Poronaysk right now. Temperature +15.7°C, atmospheric pressure 753.1 mm Hg (1004 hPa), cloud cover 21%, humidity 84%, wind 13.7 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 Poronaysk page shows both indicators side by side. Weather data from Open-Meteo (CC BY).
Aurora viewing window for Poronaysk tonight. Sunset is at 05:33 local time, sunrise tomorrow at 13:22. Moon phase — waning crescent with 8% disk illumination. Clear sky and low moonlight make the window favorable — with enough Kp, the aurora may be visible even from within city limits..
