The Northern Lights May Dazzle Across 15 States This Week—Don’t Miss It Find out if the dazzling display will be in your backyard. Close Credit: Elena Pueyo / Getty Images Key Points NOAA’s Space Weather Prediction Center forecasts minor (G1) to possibly moderate (G2) geomagnetic storms over the next two nights, which could make the northern lights visible across parts of the northern U.S.The Kp index is expected to reach 5, meaning auroras could be seen as far south as northern Michigan and Maine, depending on solar wind strength.A mix of fast solar wind from a large coronal hole and a weak coronal mass ejection (CME) is driving the heightened geomagnetic activity, creating ideal conditions for an aurora display. Bundle up and prepare for a glowing spectacle in the evening sky. The northern lights are expected to appear across parts of the U.S. over the next two nights. Forecasters at NOAA's Space Weather Prediction Center (SWPC) predict possible minor (G1) geomagnetic storm conditions tonight and tomorrow night, with the chance of a stronger moderate (G2) storm, depending on the incoming solar wind. Geomagnetic storms are ranked from G1 (minor) to G5 (extreme). The SWPC is also currently predicting the Kp index to reach a high of 5. The Kp index is a scale from 0 to 9 that's used to measure geomagnetic activity. The higher the number, the further from the poles the northern lights could appear. According to the SWPC's latest alert, the northern lights "may be visible at high latitudes, i.e., northern tier of the U.S., such as northern Michigan and Maine."

The Old Farmer’s Almanac Reveals the Holiday Forecast The combination of fast solar wind from a large Earth-facing coronal hole and a weak coronal mass ejection (CME) could cause solar wind speeds to climb significantly over the next two days, according to Space.com, resulting in a dazzling display. Based on the latest NOAA aurora forecast map, parts of Alaska, Maine, Montana, North Dakota, Minnesota, Wisconsin, Washington, Idaho, South Dakota, Michigan, Vermont, New Hampshire, Wyoming, Iowa, and New York have a chance of experiencing the phenomenon. If you're located in one of these areas of the country, head to a dark location away from light pollution and find a north-facing spot with a clear view of the horizon. Look up around midnight to 2 a.m. local time to spot the auroras. Explore more: News Space & Weather News
