Visibility III / V

Heidi Rikala, Ursa (Helsinki)

The illuminated night clouds began to show faintly already during the shadow of the Earth in the southern sky. Gradually they began to brighten and gradually they were visible in every direction. The south side had the best and brightest. The last two pictures have been taken with the camera's HDR setting. #bongaa100
