A geomagnetic storm bombarded Earth’s atmosphere Sunday, setting off the northern lights at high latitudes.
The National Oceanic and Atmospheric Administration’s Space Weather Prediction Center rated it a moderate storm, level 2 on its 0 to 5 scale.
The storm was waning when darkness settled Sunday night and aurora finally became visible in North America. But vibrant green and purple lights streaked over the Canadian skies.
“God’s glory is on tour in the skies, God-craft on exhibit across the horizon. Madame Day holds classes every morning, Professor Night lectures each evening. Their words aren’t heard, their voices aren’t recorded, But their silence fills the earth: unspoken truth is spoken everywhere. Psalm 19:1-4 MSG . My time here is drawing to a close. Yesterday, there was mostly cloud cover and smoke from the fires in British Columbia. I didn't have a lot of hope that the northern lights would make an appearance. But did they ever. #northernlights #aurora #auroraborealis #explorecanada #explorealberta #landscapephotography #astrophotography #instagood #photooftheday
In the northern United States, the hues were more subtle but still sensational.
Photographers in Maine, New Hampshire, Massachusetts, Upstate New York, Michigan, Minnesota, Wyoming, Idaho, Montana and Washington state all captured the spectacle.
The animation, below, from Mackinaw City, Mich., is particularly impressive:

The show was even better in the Southern Hemisphere, because the storm’s peak coincided with nighttime there. The image below was taken in New Zealand:

The geomagnetic storm originated from a solar flare that erupted on the sun Friday and then emitted a plume of charged particles known as a coronal mass ejection.
Such events have been rare over the past year because the sun’s activity is near a minimum in its approximately 11-year cycle.
