Dim night shining clouds - 2.7.2021 at 01.15 - 2.7.2021 at 03.00 Uusikaupunki Observation number 100066

Visibility II / V

Pirjo Koski, Porin Karhunvartijat

The night clouds seen at midnight encouraged me to go off-road and for a long time I have had the village of Kallela in Kalannin in mind.

The night clouds bounced up from the east, visible from the north as well as the south. The direction to the west was bright, but there were also familiar fibers.

These night photography trips sometimes have fun features and so it happened again ... the trip with its joyful twists can be read on my blog:
