Extremely rare 'Nacreous' or 'Mother Of Pearl' or 'Polar Stratospheric Clouds' captured before sunrise from Cookstown on February 2nd 2016.

Nacreous clouds require temps of -85 degrees C in the Stratosphere so thanks to storms Gertrude, Henry and the displacement of the Polar Vortex UK and Ireland had an unexpected rare outbreak of these clouds unlike anything seen in years, some of them even caused damage to the Ozone Layer above the UK during this time, read the report for more information. * All images are available for sale in the form of photo prints, canvas or digital files for licensing, if you are interested in a purchase simply drop me an email.
