Magnetic storms in Korosten

Magnetic storm in Korosten today: planetary Kp = 1.0 (G0). Over the last 7 days the maximum Kp above Korosten reached 4.7 (G0); storm days (G1+) this week: 0.

Korosten sits at geomagnetic latitude 48.3°. The nearest magnetic observatory continuously recording the field is Kyiv (Dymer), 119 km away. Population 61,496.

Magnetic storms and health of Korosten residents: at Kp ≥ 5 weather-sensitive people may experience pressure swings, headaches, sleep issues. Especially pensioners and people with hypertension should watch the forecast. During a storm — hydrate more, avoid alcohol and strong coffee, avoid intense physical load.

Technical consequences for Korosten at G3+: GPS, HF radio and precise positioning systems may glitch. Drivers on long routes should watch the forecast for the next 24–72 hours. Data source: NOAA Space Weather Prediction Center, refreshed every 10 minutes.

Over Korosten during the last 24 hours. Kp reached a maximum of 3.3 around 03:00 local time and dipped to 1.0. The planetary trend over the past 6 hours is falling — the magnetosphere near Korosten is in the recovery phase. So far this month the planet has logged no G1+ storm days with a G1 or stronger geomagnetic storm.

Aurora visibility threshold for Korosten. At a geomagnetic latitude of 48.3°, the minimum Kp giving a realistic chance of visible auroras above Korosten is about Kp ≥ 7. 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 Korosten right now. Temperature +13°C, atmospheric pressure 751.3 mm Hg (1001.7 hPa), cloud cover 83%, humidity 52%, wind 6.6 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 Korosten page shows both indicators side by side. Weather data from Open-Meteo (CC BY).

Aurora viewing window for Korosten tonight. Sunset is at 20:27 local time, sunrise tomorrow at 05:37. Moon phase — waning gibbous with 98% 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..
