Bright night shining clouds - 1.8.2016 at 01.00 - 1.8.2016 at 02.45 Espoo Observation number 55230

Visibility IV / V

Janne Sievinen, Ursa (Helsinki)

Fine night clouds lingered for a couple of hours north of the sun reddening the horizon. Photo taken in Nuuksio on the top of Solvalla's Swinghill ski slope. During the night, more than a hundred photos were taken with the aim of making a time series film - but even if a finger accidentally swept the focus sadly wrong at the beginning of the series ... The initial exposure experiment produced a sharp image, and the clouds were beautiful to watch live!
