Bright night shining clouds - 24.7.2019 at 23.45 - 25.7.2019 at 01.15 Espoo Observation number 84463

Visibility IV / V

Had to visit the balcony to peek at the cloud situation just before midnight. It became an outdoor trip. Admittedly, only to the nearest open place. The northeastern sky had the most spectacular night cloud formation and there they rose to a reasonably high level. In all, night clouds were visible in the area extending from west to east. Two panoramic pictures included. The pictures were taken at about one o'clock at the time, after which the show, especially in the northeastern sky, began to fade.

Tutun näköiset valaisevat yöpilvet. Kivoja kuvia!

Kiitos Eero! Todellakin samaa yöpilvilauttaa olemme kuvanneet, vaikkakin noin 100 km välimatkaa noista radiomastoista päätellen. Itse en ehtinyt viime yönä maisemallisesti kivaa paikkaa hakemaan, mutta olihan tuo koilisen lautta itsessään jo komea. Toki radiomastot vielä iso plussa kuvassa!
