The Northern Lights may be visible in the northern sky in 15 northern US states and Canada after dark on Tuesday, November 25, according to forecast from the National Oceanic and Atmospheric Administration’s Space Weather Prediction Center. The forecast includes a G1 rated geomagnetic storm.
It comes not after a solar flare or coronal mass ejection, but as Earth is buffeted by an unusually turbulent solar wind. It means an increased chance of an aurora in high latitudes, but also further south if things intensify.
Northern Lights Forecast: What to Expect
The latest forecast calls for a G1 geomagnetic storm after dark in North America on Tuesday, November 24, extending into the morning hours of Wednesday, November 25.
NOAA provides that “the geomagnetic field is expected to continue at unstable to active levels, with possible G1 (Minor) geomagnetic storms, on November 24.
According to NOAA aurora line of sight15 states could see displays of the Northern Lights in the northern sky.

Northern Lights Forecast: Where and When
The latest from NOAA Sunshine show that an aurora is possible in northern US states and Canada, with 15 US states getting a chance after dark on Tuesday, November 25.
US states that may see auroras include Alaska and (northern parts of) Washington, Idaho, Montana, Wyoming, North Dakota, South Dakota, Minnesota, Iowa, Wisconsin, Michigan, New York, Vermont, New Hampshire and Maine.
Urban glare is aurora’s worst enemy. For the best view, locate a dark place using it Dark Sky Location Tracker and a light pollution map. The darker the northern sky, the more vivid the display — even during moderate geomagnetic storms.

Aurora hunters often use the Kp index to predict the intensity of a geomagnetic storm, but for aurora monitors, the Bz component of the interplanetary magnetic field is more important (you’ll find it in some of the above applications and in SpaceWeatherLive.com). Bz determines how easily solar energy enters the Earth’s magnetosphere. When Bz points north, the Earth’s field resists. when the Bz oscillates south, the two fields connect, allowing the plasma to enter. A stable southward Bz of −5 nT or stronger usually signals an impending aurora.

Northern Lights: Why To Travel For The Best Displays
To almost ensure the Northern Lights, aim to be below the auroral oval, which stretches between 60 and 75 degrees latitude. This includes Alaska, northern Canada, northern Norway, Sweden, Finland and Iceland. At these latitudes, auroras are visible several nights a week from September to March.
However, clear weather is impossible to guarantee. Stay for at least three nights to improve your chances and check local forecasts before heading out.
I wish you clear skies and open eyes.
