Some residents in Okanagan Valley, British Columbia, were briefly enveloped in shades of pink and purple on Wednesday morning, 31 January.
The city of Kelowna experienced rare pink and purple-hued fog for several minutes around 7:30am PT before the sky returned to its normal grey colour.
Canada Broadcasting Corporation (CBC) podcast host Bob McDonald explained the rarely-seen phenomenom, saying “The phenonomen is when sunlight passes through a lot of material that’s in the air, whether it’s dust or it’s moisture.”
“The shorter wavelengths, blues and greens, they get scattered more easily - that’s why we have blue skies.”
He then explained that red light penetrates dust better, which results in the pink sky.
