Magnetic storms in Merefa

Magnetic storm in Merefa today: planetary Kp = 1.0 (G0). Over the last 7 days the maximum Kp above Merefa reached 5.7 (G1); storm days (G1+) this week: 3.

Merefa sits at geomagnetic latitude 46.1°. The nearest magnetic observatory continuously recording the field is Kyiv (Dymer), 421 km away. Population 21,202.

Magnetic storms and health of Merefa 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 Merefa 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 Merefa during the last 24 hours. Kp reached a maximum of 2.7 around 03:00 local time and dipped to 1.0. The planetary trend over the past 6 hours is steady — no sharp changes near Merefa right now. So far this month the planet has logged 3 days with a G1 or stronger geomagnetic storm.

Aurora visibility threshold for Merefa. At a geomagnetic latitude of 46.1°, the minimum Kp giving a realistic chance of visible auroras above Merefa 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 Merefa right now. Temperature +5.4°C, atmospheric pressure 742.2 mm Hg (989.5 hPa), cloud cover 100%, humidity 62%, wind 21.9 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 Merefa page shows both indicators side by side. Weather data from Open-Meteo (CC BY).

Aurora viewing window for Merefa tonight. Sunset is at 19:42 local time, sunrise tomorrow at 05:25. Moon phase — first quarter with 49% 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..
