Must See: Iqaluit wakes up to pink skies. Here's why

Friday, January 15, 2016, 1:02 PM - Residents of Iqaluit, Nunavut were treated to a spectacular red sky Tuesday morning.

A curious pink hue took over the city which led to a social media frenzy, with many posting photos of the sky with the hashtag #nofilter.

This comes days after Twitter and Facebook erupted with photos of a stunning sunrise across Ontario.

Why were the colours so vivid in Iqaulit? The Weather Network's meteorologist Dayna Vettese has the answers.

"Colours seen in the sky have to do with the sun's rays of light being split into the different colours of the spectrum as they pass through particles and water vapour in Earth's atmosphere," she said. "The concentration of water vapour and other particles will impact the colours seen and how vibrant they are. The sun is low in the sky during sunrise and sunset so the light is being transmitted through the thickest part of the atmosphere."

Pollutants have an effect on how the hues are displayed, Vettese adds.

"For vivid and bright sunrises, you want the air to have a low concentration of pollutants...The fact that it is winter makes for a more vivid sunrise because the air is typically drier and cleaner."

Vettese says if there is a red sky during the morning hours that is a good indication that there may be a low pressure system on the way.

"When there is a red, pink, or orange hue to the sky that means the sun's rays are passing through a high concentration of moisture and particles. The more moisture, the more likelihood of a weather system approaching. If the sky is red at night, often times that means that there is stable air in place so good weather will follow. With a red sky in the morning, that generally can mean high pressure is passing so a low pressure system is on its way."
