Magnetic storms in Utah
Magnetic storms in Utah, United States. Current Kp index, 3-day storm forecast, list of cities and geomagnetic activity.
Cities in region1/1
An aurora visible over Utah requires Kp ≥ 7 — current activity is below that level.

FAQ about magnetic storms in Utah
Are auroras visible in Utah?+
Rarely. The geomagnetic latitude of Utah (≈ 47.7°) is not high enough for regular auroras. They are possible only during strong storms Kp ≥ 7 (G3–G4), a few times a year.
How do magnetic storms affect residents of Utah?+
At Kp ≥ 5 weather-sensitive people may experience blood pressure swings, headaches, sleep disturbances. Effects are moderate due to low geomagnetic latitude. However, strong G3+ storms can cause noticeable discomfort even here.
What Kp is needed to see an aurora in Utah?+
By our estimate — Kp ≥ 7 (based on the regional mean of 47.7° geomagnetic latitude). The threshold is lower in the north of the region and higher in the south. For a specific city, open its page and check the «Aurora visibility threshold» section.
Where is the best place to watch auroras in Utah?+
Best conditions are at the northernmost city in our database (Salt Lake City, 40.8° N). The further north, the higher the geomagnetic latitude and the more frequent the auroras. Also important: clear sky, no city light pollution, and observation around local midnight.
What is the nearest magnetic observatory?+
The nearest observatory is Paratunka (Kamchatka), at 6506 km from the centre of Utah. It belongs to the INTERMAGNET network and records the geomagnetic field in real time.
About magnetic storms: Utah
Magnetic storms in Utah (United States) today: planetary Kp = 2.7 (quiet). The database holds 1 cities in the region with live geomagnetic data and forecasts.
Pick a city from the list to see detailed information: local time, geomagnetic latitude, distance to the nearest magnetic observatory, 3-day Kp chart with forecast and aurora visibility chance. All cities in Utah use the same planetary Kp, but the local impact is computed individually per coordinates.
How a magnetic storm may manifest in Utah: at Kp ≥ 5, weather-sensitive people can have headaches, blood-pressure swings, sleep disruption. At Kp ≥ 7, GPS navigation and shortwave radio may glitch. At Kp ≥ 8 — power-grid issues. Data from NOAA SWPC, updated every 10 minutes.
Inside Utah, geomagnetic latitude varies from 47.7° to 47.7°, with a mean of 47.7°. The northernmost city, Salt Lake City, gets aurora visibility opportunities first when Kp climbs; the 0.0° south-to-north spread is enough to put neighbouring cities into very different storm-response groups.
The nearest magnetic observatory tracking conditions over Utah is Paratunka (Kamchatka). Combined with the planetary Kp index from NOAA SWPC, this station gives the closest reference point for how the local magnetic field behaves during storms in this part of United States.
