Svetlana Kazina, who lives in the Altai Mountains, snapped these breathtaking pictures of the glowing sky over Belukha mountain, Siberia’s highest peak (4,506 metres/14,783ft).
The images show thin clouds resembling soap bubbles in colours.
Iridescent clouds, also known as rainbow clouds, occur when sunlight scatters through water droplets in the atmosphere.

‘I pictured this beauty over Siberia’s highest peak, Belukha, early in the morning’, said Svetlana.
‘Rainbow clouds are a rare optical phenomenon when thin clouds close to the Sun change to spectral colours.
‘The clouds in my photos are so thin that they look more like lace.
‘The wind at this height was so strong that the cloud ‘lace’ changed every second.’
The Altai Mountains in southern Siberia include some of Russia’s most stunning scenery, a haven for travellers who want to escape from the modern world.
