The Northern Lights, or auroras, may be visible across up to 15 states in the U.S. this Valentine's Day weekend, with the best viewing chances on Sunday night. The forecast predicts a G1 geomagnetic storm caused by a coronal hole on the sun and a coronal mass ejection arriving on Earth, which could trigger auroras in states including Alaska, Washington, Idaho, Montana, Wyoming, North and South Dakota, Minnesota, Wisconsin, Michigan, New York, and Maine. The Kp index is expected to peak at 4.67, indicating the potential for auroras to be seen further south than usual. Skywatchers are advised to head outside between 10 p.m. and 2 a.m., look north, and find a clear, dark horizon away from light pollution. The activity is linked to the Earth's proximity to the spring and fall equinoxes, which increase geomagnetic activity due to solar wind interactions. Photos and videos of auroras can be uploaded to local community galleries. The phenomenon is more likely during periods of increased solar activity, especially around the equinoxes, when the Earth's magnetic field is more susceptible to solar wind disturbances.
