Bright night shining clouds - 4.8.2021 at 00.30 - 4.8.2021 at 02.20 Lahti Observation number 100187

Visibility IV / V

Late summer is already visible in the night clouds. What has been lost in height and extent has been taken back in glory. I wonder if these are bright or eye-catching. However, I ended up on the bright side.

Kauniit ja kirkkaat olleet sielläkin. Ja tosiaan sen punertava yläreuna näkyy.

Kelpaisi kyllä tuolla paikalla vanhoja radiolähetteitä kuunnella kauniiden yöpilvien loisteessa :-) Vaan on lähettimet nykyään sammuneet...
