Timelapse: Northern Lights visible in Sonoma County

(KRON) — The aurora borealis was visible in the northernmost region of the Bay Area Saturday night and early Sunday morning.

Local photographer Alexander Glavtchev sent these images of last night’s Northern Lights from Windsor, Calif. Watch the video at the top of this story for a timelapse of the event.

There’s another chance the northern lights will be visible in northern Sonoma County between Sunday night and early Monday morning. Stargazers in the city won’t be able to view the lights. However, the lights may be visible online using AlertWidlfire cameras.

The Northern Lights occur when energetic particles from the sun collide with atoms and molecules in the Earth’s atmosphere, creating glowing colorful skies, according to NASA.

“Auroras, also known as the northern or southern lights, are colorful and dynamic displays that glow in the night sky,” the NASA website reads. “Auroras occur in an upper layer of Earth’s atmosphere called the ionosphere, but they typically originate with activity on the sun. Occasionally, during explosions called coronal mass ejections, the sun releases charged particles that speed across the solar system.”

The best regions for viewing tonight’s aurora borealis are highlighted in a map provided by the National Oceanic and Atmospheric Administration.
