Magnetic storms in Yuzhno-Sakhalinsk

Magnetic storm in Yuzhno-Sakhalinsk today: planetary Kp = 0.7 (G0). Over the last 7 days the maximum Kp above Yuzhno-Sakhalinsk reached 5.7 (G1); storm days (G1+) this week: 3.

Yuzhno-Sakhalinsk sits at geomagnetic latitude 39.1°. The nearest magnetic observatory continuously recording the field is Paratunka (Kamchatka), 1292 km away. Population 198,973.

Magnetic storms and health of Yuzhno-Sakhalinsk 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 Yuzhno-Sakhalinsk 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 Yuzhno-Sakhalinsk during the last 24 hours. Kp reached a maximum of 2.7 around 11:00 local time and dipped to 1.0.

Aurora visibility threshold for Yuzhno-Sakhalinsk. At a geomagnetic latitude of 39.1°, the minimum Kp giving a realistic chance of visible auroras above Yuzhno-Sakhalinsk is about Kp ≥ 9. 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 Yuzhno-Sakhalinsk right now. Temperature +0.9°C, atmospheric pressure 762.1 mm Hg (1016 hPa), cloud cover 0%, humidity 79%, wind 2.3 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 Yuzhno-Sakhalinsk page shows both indicators side by side. Weather data from Open-Meteo (CC BY).

Aurora viewing window for Yuzhno-Sakhalinsk tonight. Sunset is at 04:28 local time, sunrise tomorrow at 14:25. Moon phase — first quarter with 49% disk illumination. Clear sky and low moonlight make the window favorable — with enough Kp, the aurora may be visible even from within city limits..
