A spectacular and beautiful cloud formation was spotted in the skies above Australia by a passenger on an aeroplane.
Ilya Katsman, 22, saw the phenomenon on a Virgin Australia flight from Perth to Adelaide.
A spokesperson from the Met office explained to The Telegraph that the cloud is of a type commonly seen in Australian skies, but they are rarely as beautifully distinctive as this example.
Ms Katsmann wrote on Instagram: "The most unique cloud formation I have seen to date on route from Perth to Adelaide somewhere over The Great Australian Bite".
Virgin Australia posted a selection of photographs, writing: "Flying above the clouds has never looked this good! These incredible cloud formations were seen on board VA714 from Perth to Adelaide."
A Met Office spokesperson explained the cloud to The Telegraph.
He said: "In terms of how they form, it's about air rising, cooling and then descending again.
"They're most commonly seen in Australia and are most commonly associated with sea breeze condensation.

"The rising, cooling and falling of atmospheric waves creates the thin strips of clouds.
"This cloud is quite a graphic demonstration of it."
These clouds could be seen in the UK, but are rarer here.
The Met office spokesperson said: "We have seen them in the UK before, but not as commonly".
Clouds such as these are locally known as 'morning glory'.
