Rare clouds - 23.7.2021 at 02.17 - 23.7.2021 at 02.43 Helsinki Observation number 99857

Visibility I / V


Once accustomed to mindless, absurd, and utterly incomprehensible performances, the marginal performances feel strange. The air was clear and ideal for nega, but due to / thanks to the Jokerity site, another bend had to be made on the observation route. In the forest cavity in the northwest, the eye then separated something and had to check and follow up. They were dim, but the eye still recognized potential spots. The height was less than 15 degrees. If the delicate patterns at the top of the last picture are accepted as night clouds, then they would already be at 30 degrees. - The support findings would be nice. Based on the direction, the pictures taken around Turku should show the same streaks a little higher. In Denmark, an observation has been made of delicate streaks at a low 00: 10CET. The elongated spray in Figure 5 moved fairly quickly and is most obviously a norm cloud.

Turku kuittaa. Tuollaista näkyi kuin kolmoskuvassa, en tohtinut yrittää kuvata.

Itse olin reilua tuntia aiemmin liikenteessä enkä nähnyt yhtään minkäänlaista merkkiä yöpilvistä.

Ennen kahta pohjoisessa oli heikkoa hehkua, mutta kuvista ei irronnut kontrastijuovia enempää. Taivaan taustavalokaan ei enää häiritse. Aina kannattaisi räpsäistä varmistukuva tai pari negaakin varten. Eikä koskaan tiedä, vaikka saisi napattua salayökkösen.

Hyvin himmeästi ne näkyivät täälläkin. Ei vain tullut kuvia otettua edellisen spektaakkelin vielä hivellen silmiä.

Otin kuvan kyllä varmuuden vuoksi, liitin sen mukaan negatiiviseen havaintooni. Ei siitä kyllä mitään erottanut.
