Summary
The northern lights might be visible over parts of the U.S. tonight because a solar event known as a coronal mass ejection (CME) is expected to reach Earth. This could lead to a geomagnetic storm allowing people in certain northern U.S. states to see the lights. The lights might also appear tomorrow, depending on weather conditions.
Key Facts
- A coronal mass ejection (CME) is an eruption from the sun, releasing plasma and a magnetic field.
- This CME may cause a geomagnetic storm, making the northern lights visible in the U.S.
- The geomagnetic storm is rated as G2-class by NOAA.
- The northern lights could be seen in states such as Idaho, Maine, and New York.
- Viewing is best just after sunset or right before sunrise.
- Northern lights are not visible during daylight.
- Clear skies and areas free of light pollution improve viewing chances.
- Another storm, rated G1-class, is expected the following night.
