A geomagnetic storm caused by a solar activity on Wednesday may bring the northern lights visible in Alaska and parts of Washington, Idaho, Montana, North Dakota, South Dakota, Minnesota, Wisconsin, Michigan, and Maine tonight.
Stargazers in these states will have the best chance of viewing the aurora borealis, which is expected to occur between 10 p.m. and 2 a.m. local time. To witness the phenomenon, it’s recommended to move away from light pollution and find a high vantage point.
The northern lights are caused by charged particles from solar activity interacting with Earth’s atmosphere, resulting in a colorful display of different colors due to collisions with oxygen and nitrogen particles.
This event coincides with the Blood Worm Moon total lunar eclipse, which begins just before midnight EDT on March 13. Stargazers can also view this phenomenon, which occurs when the moon passes into the darkest part of Earth’s shadow.
The National Oceanic and Atmospheric Administration (NOAA) has predicted a Kp index of four out of nine tonight, indicating moderate geomagnetic activity.
