DID you see these incredibly rare clouds this morning over York?
Many readers have been in touch and kindly sent us amazing photos showing rare 'rainbow' clouds in the sky.
Danny Knight emailed with a photo showing rainbow colours in the sky and to tell us how these are rare nacreous clouds - last seen in the UK in 2016.
He said they were a rare formation of ice crystals which only form below -78⁰C.
"They have been above York all morning and were most striking when the sun was blocked behind an obstruction or when viewed through a polarised filter.
"The last time clouds like this were widely reported above the UK was 2016."
Several members of our Press Camera Club also posted pictures of the special spectacle.
