Clearly visible night shining clouds - 2.6.2015 at 00.35 - 2.6.2015 at 02.00 Turku Observation number 38473

Visibility III / V

Juuso Nurmio, Ursa (Länsi-Suomi)

The first night clouds of a season are always the hardest to tell when you never remember what they look like from the previous season. If these are the nights now, then the season started with a pretty rumble. That is why there is little doubt to claim these as night clouds, when we cannot be pampered immediately with such a show. Isn't it?

Figure 1: 1:02

Picture 2: 0:50

Picture 3: 0:42

Before these images, the possible night clouds were still really only at a degree of distant doubt. As soon as half past one, however, began to appear.

EDIT: I watched the show for two until I had to go to bed. At this point, the clouds were slightly dimmed compared to the best moment, but still easily met the definition of "clearly visible night clouds." Hopefully here was a representative sample of the nights of the coming season, as these are worth watching.

Eipä noissa mitään polarisaatiosuodattimia tarvita.

Hyvähyvähyvä! Harmi vaan, että itse missasin nämä :( 

No, vielä on kesää jäljellä :)

Nyt kai voi jo onnitella ensimmäisestä tämän vuoden yöpilvihavainnosta, joten onnittelut Juuso!  Jollei sitten joku havainto vielä tupsahda edellesi :)

Vau! Olisi pitänyt hillua myöhempään ulkona. Jäi päässä soimaan tuo "vielä on kesää jäljellä". Meinasin lähteä uudelleensanoittamaan biisiä, mutta niin harva asia rimmaa yöpilvien kanssa. O_o

Kiitokset onnitteluista. Myönnettäköön, että on näitä kytätty ja ei tämä nyt ihan vahingossa tullut; olen jo pari viikkoa ennen nukkumaanmenoa tarkastanut pohjoistaivaan yöpilvien varalta, jos vain on selkeää ollut. Totta kai vähän tuuriakin tarvittiin, että sattui nyt riittävän selkeä yö.
