Magnetic storms in Yaroslavl

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

Yaroslavl sits at geomagnetic latitude 53.1°. The nearest magnetic observatory continuously recording the field is Borok, 109 km away. Population 608,722.

Magnetic storms and health of Yaroslavl 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 Yaroslavl 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 Yaroslavl 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 Yaroslavl right now. So far this month the planet has logged 3 days with a G1 or stronger geomagnetic storm.

Aurora visibility threshold for Yaroslavl. At a geomagnetic latitude of 53.1°, the minimum Kp giving a realistic chance of visible auroras above Yaroslavl is about Kp ≥ 6. 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 Yaroslavl right now. Temperature +5.4°C, atmospheric pressure 738.2 mm Hg (984.2 hPa), cloud cover 92%, humidity 48%, wind 12 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 Yaroslavl page shows both indicators side by side. Weather data from Open-Meteo (CC BY).

Aurora viewing window for Yaroslavl tonight. Sunset is at 19:50 local time, sunrise tomorrow at 04:46. 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..
