Did you spot these brightly coloured, ethereal clouds above Chester?
Nacreous clouds, or mother-of-pearl clouds, could be spotted above the region as early risers were treated to the display on Monday (February 1).
Such is their spectacular glow, there had been some false Aurora Borealis reports coming in across the north of England.
Twitter account @DevaChester captured some fantastic photos above the city, while Neil Cooper was able to snap them over Chester Business Park.
Nacreous clouds form above 70,000ft when extreme cold temperatures cause ice crystals to form.
Usually they are spotted at high latitudes in Scandinavia, Iceland and Canada, but it is believed high winds from Storm Gertrude and Storm Henry have brought them further south.
They are brightest at sunset and dawn because while it’s dark on the ground, up in the lower stratosphere they are still sunlit.
Refracted light off the crystals creates the iridescent colours we see way down below.
Did you take a snap of the nacreous clouds? If so we would love to add your images to our gallery.
