▸About magnetic storms in United States
Magnetic storms in United States today: planetary Kp = 0.7 (G0). Our database holds 38 regions and 136 cities of United States with live geomagnetic data.
Kp is planetary and identical everywhere on Earth, so its value for any point in United States is 0.7. But the local impact of a storm depends strongly on geomagnetic latitude: in the far north even a minor G1 storm triggers auroras and noticeable field disturbance, while in southern regions the effect is barely perceptible.
Pick a region above to see its cities. Each city page shows: current Kp and G-class, a 3-day hourly forecast, distance to the nearest magnetic observatory, local time in the correct time zone and aurora visibility chance. Data from NOAA SWPC, refreshed every 10 minutes.
