Striking red skies at sunset and UFO flying saucer-like lenticular clouds were visible from parts of Scotland on Wednesday.
Lenticular clouds form when the air is stable and winds blow across hills and mountains from a similar direction at different heights through the troposphere, according to the Met Office.
