Clearly visible night shining clouds - 8.7.2018 at 00.28 Espoo Observation number 75138

Visibility III / V

Janne Sievinen, Ursa (Helsinki)

Moderately clear night clouds, which I watched between about 00:15 and 01:10 in the port of Haukilahti in Espoo. In the attached image taken at 00:28, the histogram is (calmly) adjusted so that the fine structure of the clouds is slightly more noticeable than visually.
