Hyvin heikkoja yöpilviä - 31.7.2021 at 03.00 - 31.7.2021 at 03.30 Nousiainen
Observation number 100104
Under good observation, I would almost say the rest of the night was negative. However, during the reported observation period, very weak night clouds appeared to the north.
Even then, for the first time, I misled the night cloud image because I was noticed so weak less often.
