Aurora Borealis May Illuminate Skies Over 18 U.S. States Tonight

The night sky might offer a spectacular sight tonight, as both Canada and several parts of the United States could witness the captivating dance of the northern lights.

This celestial event is triggered by a coronal mass ejection, an explosion from the sun that occurred recently. Expected to interact with Earth’s magnetic field late Monday or early Tuesday, this phenomenon could create a mesmerizing light show, as reported by NOAA.

Eighteen states may catch a glimpse of this natural spectacle, either in hues of green or red, painting the night sky.

While not predicted to match the intensity of future displays expected next year, this occurrence still provides one of the year’s better opportunities to enjoy the lights, especially since similar events were last prominent in spring.

Understanding the Northern Lights

Known as auroras, these light shows are mostly seen in polar regions where charged solar particles collide with the Earth's atmospheric particles, leading to vibrant displays.

The sun undergoes an 11-year cycle that results in its poles reversing positions, causing magnetic distortions. Currently, the sun is in an active phase, set to continue at least until the year ends.

During the spring of 2024, Earth was hit by a powerful geomagnetic storm—the strongest observed in 20 years—resulting in stunning auroral shows across the northern skies. Similarly, last autumn also saw vigorous solar activity illuminating areas distant from the Arctic.

Visibility Predictions for the Auroras Tonight

Forecast models from NOAA suggest that the geomagnetic storm will reach its peak between 2 a.m. and 5 a.m. Eastern Time on Tuesday.

If you're within the outlined visibility zone according to NOAA's map, you might get to see nature’s light show firsthand.

Tips for Viewing the Auroras

Seek out a tranquil, dimly lit location away from the interference of artificial city lights. A visit to a nearby national or local park can enhance your viewing experience. Moreover, ensure to check weather predictions, as clouds have the potential to obscure this celestial wonder.
