It's been just over three weeks since Albertans saw an unusually bright aurora borealis shine over their skies on Oct. 12 — and early Thursday morning, they got another spectacular display.

These displays were courtesy of a moderate geomagnetic storm, according to the U.S. National Oceanic and Atmospheric Administration. Geomagnetic storms are changes in the Earth's magnetic field caused by solar flares.

AuroraMAX, a federally-funded observatory in Yellowknife, N.W.T., said in a Facebook post on Wednesday that the northern lights would be visible in most provinces and territories on Nov. 3 and 4. There was some activity seen Wednesday evening in Alberta, but it was more prominent after midnight.

There was also a display across parts of Canada on the weekend of Oct. 30 and 31. 

The aurora borealis happens when particles from the sun are carried toward the planet's ionosphere, and those particles collide with gas particles, releasing energy that's visible as light.

Auroras are usually seen only in polar regions, but particularly large bursts of solar energy — or coronal ejections — have caused the aurora to be seen much farther south than usual.

If you're looking for something to brighten your day, here are some photos of the aurora on Thursday morning that Albertans shared with CBC Calgary.
