Magnetic storms in Los Angeles

Magnetic storm in Los Angeles today: planetary Kp = 0.0 (G0). Over the last 7 days the maximum Kp above Los Angeles reached 5.7 (G1); storm days (G1+) this week: 3.

Los Angeles sits at geomagnetic latitude 40.3°. The nearest magnetic observatory continuously recording the field is Paratunka (Kamchatka), 6646 km away. Population 3,820,914.

Magnetic storms and health of Los Angeles 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 Los Angeles 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 Los Angeles during the last 24 hours. Kp reached a maximum of 2.7 around 17:00 local time and dipped to 1.0. The planetary trend over the past 6 hours is steady — no sharp changes near Los Angeles right now. So far this month the planet has logged 3 days with a G1 or stronger geomagnetic storm.

Aurora visibility threshold for Los Angeles. At a geomagnetic latitude of 40.3°, the minimum Kp giving a realistic chance of visible auroras above Los Angeles 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 Los Angeles right now. Temperature +13.6°C, atmospheric pressure 751.5 mm Hg (1001.9 hPa), cloud cover 15%, humidity 73%, wind 7.6 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 Los Angeles page shows both indicators side by side. Weather data from Open-Meteo (CC BY).

Aurora viewing window for Los Angeles tonight. Sunset is at 09:31 local time, sunrise tomorrow at 20:10. Moon phase — first quarter with 48% disk illumination. Clear sky and low moonlight make the window favorable — with enough Kp, the aurora may be visible even from within city limits..
