Bright night shining clouds - 1.8.2020 at 01.25 Orimattila, Artjärvi, Tähtikallio Observation number 92806

Visibility IV / V

Toni Veikkolainen, Keski-Uudenmaan Altair

On the first night of the Star Rock work, night clouds appeared near the northern horizon at an altitude of less than 10 degrees, and they had to be photographed. The contrast to the already pretty dark sky was quite, and in a way, these late summer night cloud plays can be finer than the early summer.
