There were even reports of the phenomenon being seen as far away as Leicestershire.
The colourful pattern got Twitter wags talking, with some suggesting it was the start of an alien invasion.
Others with cooler heads suggested it was a phenomenon known as cloud iridescence.
The BBC reported that the clouds were known nacreous - otherwise known as mother-of-pearl.
