Look during your location’s darkest hours. Aurora can occur at any time of night, so use local twilight and current conditions.
September - March when nights are longest. October and March around equinoxes often show increased activity.

Check our live visibility map above showing current Kp index and cloud cover. Aurora borealis is visible in Alaska when Kp reaches 1-3, northern states at Kp 4-5, and southern states during rare Kp 7+ events.
Aurora borealis is best visible between 10 PM and 2 AM when skies are darkest. Our live tracker shows the optimal viewing window for your location based on sunset, moonrise, and current geomagnetic activity.
Tonight's best aurora borealis visibility is in Alaska (Fairbanks, Anchorage). During stronger storms (Kp 5+), visibility extends to Washington, Minnesota, Maine, and occasionally the Great Lakes region.
Open your city forecast to compare geomagnetic conditions, cloud cover, moonlight, and darkness. Status labels are planning aids; clear local skies and a visible display are never guaranteed.
Four factors determine visibility: (1) Kp index must reach your location's threshold, (2) Cloud cover below 30%, (3) No moonlight interference, (4) Full astronomical darkness. All factors shown in our forecast.
Strong geomagnetic storms can make aurora visible much farther south than usual. Southern visibility depends on storm strength, local sky conditions, and the observer’s horizon.
No special equipment needed - aurora borealis is visible to the naked eye. However, binoculars can enhance detail, and cameras capture colors better than human eyes. A red flashlight preserves night vision while checking your phone.
Cloud cover, light pollution, a blocked northern horizon, moonlight, and changing geomagnetic conditions can all prevent a sighting. Recheck current source data and local weather before going out.
Aurora borealis requires full darkness for visibility. Astronomical twilight (sun 18° below horizon) offers the best conditions. Alaska has extended twilight in summer, making September-March the prime aurora season for most of USA.
To the naked eye, aurora borealis often appears as a pale green or white glow on the northern horizon. Brighter displays show distinct curtains, arcs, and pillars. Cameras capture more vivid colors due to longer exposure times.
Aurora and cloud conditions can change quickly. Check the latest NOAA product and your local forecast close to your viewing time.
No, aurora borealis requires clear skies. Even thin high clouds significantly reduce visibility. Our forecast includes NOAA cloud cover predictions to help you find clear sky windows for aurora viewing.
