Magnetic storms in Houston

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

Houston sits at geomagnetic latitude 38.3°. The nearest magnetic observatory continuously recording the field is Magadan (Stekolnyi), 8368 km away. Population 2,314,157.

Magnetic storms and health of Houston 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 Houston 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 Houston during the last 24 hours. Kp reached a maximum of 2.7 around 19:00 local time and dipped to 1.0. The planetary trend over the past 6 hours is steady — no sharp changes near Houston right now. So far this month the planet has logged 3 days with a G1 or stronger geomagnetic storm.

Aurora visibility threshold for Houston. At a geomagnetic latitude of 38.3°, the minimum Kp giving a realistic chance of visible auroras above Houston 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 Houston right now. Temperature +21.7°C, atmospheric pressure 754.9 mm Hg (1006.4 hPa), cloud cover 7%, humidity 92%, wind 6.8 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 Houston page shows both indicators side by side. Weather data from Open-Meteo (CC BY).

Aurora viewing window for Houston tonight. Sunset is at 11:53 local time, sunrise tomorrow at 22:45. 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..
