Colourful edges on the lowering Sun in La Silla

Dramatic sunset caught from ESO La Silla Observatory with incredibly clear skies over the horizon, allowing to capture several unique moments of so-called green and blue flashes before the Sun disappeared. The upper view shows the sun just a minute before sunset, the lower insets were taken very quickly (5 images per second) to get as many as possible moments of the blink-eye-time sunset color-flashing sequence. Captured on 1 July 2019.
