New rainbow clouds reported on the BBC, they look pretty amazing:
Rare 'rainbow cloud' spotted in UK skies
Residents in Scotland were amazed by a rare sight in the sky on Tuesday evening.
Looking like a "portal to the next dimension" or possibly a spaceship, the shimmering colours of nacreous cloud were spotted.
One of the highest clouds in our atmosphere, they are often referred to as "mother-of-pearl", and are rarely spotted in the UK because of the exceptional conditions needed.
Nacreous cloud form in very cold conditions over polar regions and within the stratosphere, around 12-19 miles (19-31km) high, for above our normal clouds.
BBC Weather Watcher SazzyJ "spotted this cloud iridescence from our garden in Edinburgh late afternoon. We'd never seen anything like it before".
"A portal to the next dimension" said Weather Watcher SkyWatcher.
Another commented "Brief, eerie and bright cloud illumination at sunset this evening. Unsure exactly what. No filter, no spaceship."
