The Prairies Climate Change Project is a joint initiative between CBC Edmonton and CBC Saskatchewan that focuses on climate and our altering local weather. Meteorologist Christy Climenhaga brings her knowledgeable voice to the dialog to assist clarify climate phenomena and local weather change and the way they affect on a regular basis life.


The northern lights lit up the sky throughout North America on Thursday, with sightings reported as far south as New Mexico. 

It was one more spectacular aurora show, in what has been a busy spring to this point.

“It was just absolutely insane,” mentioned Matt Melnyk, who has been photographing auroras for greater than 15 years in southern Alberta.

He caught the latest present.

“Different colours bursting with pillars, and I got to see pinks, purples, reds, greens, everything. It was pretty remarkable.”

Aurora forecasters say the latest present was surprising and stronger than most we have seen lately. Melnyk mentioned it was a uncommon sight, particularly for these additional south.

Auroras are measured on a KP degree index between one and 9. Thursday night time hit degree eight, which is extraordinarily uncommon, Melnyk mentioned. 

Cathleen Mewis was additionally in a position to catch the present on Thursday night time. 

She images auroras close to Saskatoon and is part of the Saskatchewan Aurora Hunters Facebook web page. 

“I hummed and hawed, should I go out?” she mentioned.

“I got in my car and I drove out and I had a spot in mind to go to a church and I didn’t even make it there because the sky just exploded,” she mentioned. 

The sky filled with northern lights.

Mewis mentioned she was out early for aurora searching on Thursday and was in a position to catch the lights at round 8:45 p.m. She mentioned it was among the finest she’s seen but. 

“It was barely sunset and it was just crazy … reds and blues and it was just amazing,” she mentioned.

“People can’t understand the experience until you’re standing there watching it and it’s just … it’s just awe inspiring.”

Lots of lights currently

Aurora exercise is tied to exercise on the floor of the solar. When the solar releases photo voltaic flares and photo voltaic wind towards Earth it interacts with our magnetic subject and environment.

Those photo voltaic storms may cause a lot of points on earth. Strong photo voltaic storms may cause electrical failures and issues with GPS and communication, even satellite tv for pc launch failures. 

But lively auroras are one of many extra spectacular side-effects. 

“That energy shows itself by shooting electrons down our magnetic field line,” mentioned Bill Archer, a mission scientist with the Canadian Space Agency.

“It hits our atmosphere and it lights it up as if it were a neon light.”

The show on Thursday night time was the product of an exceptionally robust geomagnetic storm — a disturbance of the Earth’s magnetic subject. 

And it is just the start in response to Archer. As the solar turns into extra lively, seeking to peak in exercise in 2025, he mentioned that we may see a number of the strongest storms in years.

“Right now we’re moving into a solar maximum, which means it’s more likely that things like that are going to happen,” he mentioned

“Not only will we see more auroras, but the aurora that we see will be stronger.”
