Clearly visible night shining clouds

27.6.2022 at 00.46 - 02.25 - Helsinki (III)
Pentti Arpalahti

At half past one, the night first looked like a version of the previous two nights. There is a hint in the second picture 0:32 but not enough for identification. In the northern triangle 0:46, the observation was visually certain. From there it then expanded. The first image I took 0:54 (illustration-type editing is not a scientific record corresponding to visual observation). Vito's North 2:14 is at the end of the show. I chose 1/8 for the extent, although 1/16 of the entire visible sky area would be more accurate, but the area was not very small.

Dim night shining clouds

Stir? Northwest belt. Edit. No need to update the rating. The performance was really dim. There was a belt in the northwest that showed up from 0:59 to 1:14. In the northeast, there was a 1:29 belt that was suitably in the area of influence of the pola. I checked 1:49 northwest and a small group in the east popped out of the picture. There was nothing in the north.

Hyvin heikkoja yöpilviä

At first it seemed that he would be able to do a very reliable negan. But 1:22 the eye separated the light spot on the north edge of the brown strip. As I watched the situation unfold, a swirl separating from the brown into the elevator stood out on the back of the camera. The editing also revealed thin belts. I steeled the first image of the sky with the worms. The streaks remained very dim when the morning was already beginning to dawn. There were a couple of strips in the northeast, but neither of them was really explained.

Stir. Clear skies in the clear sky at an altitude of 15 degrees in the north. Edit. Graceful wave groups also appeared. Before fading after half past two, the show remained petty.

A piece of 22r chopped between the tops of the trees.

Dim night shining clouds

There were some standard clouds in the sky, but not too much to block observation. There was a pretty group between west and northwest. There were individual groups of waves and belts between the north and the northeast. In Figure 6, I gave a large dose of usmi to expose the wave groups. I marked with a circle a spot that stood out with my eyes lighter than the background, I could not see the waves.

Clearly visible night shining clouds

21.6.2022 at 00.35 - 02.25 - Helsinki (III)
Pentti Arpalahti

The sky was quite clear, so it was supposed to pop in at nearby locations for safety. Only half of one window already showed the first belts at a height of 15 degrees. Outdoors at 0:45 the scope of the show was revealed. It was only necessary to take a few samples in different directions, but the terrain observation continued until 1:27, with night clouds everywhere. The belts stood out of the window in the northwest direction for another hour -> 2:25.

Clearly visible night shining clouds

16.6.2022 at 00.53 - 01.25 - Helsinki (III)
Pentti Arpalahti

The show was appropriately focused on the darkest part of the sky in the northeast-east direction. I just got the best time to take pictures 0:53 - 1:09. The best moment lasted only a quarter. In the east, the waves were still visible at 1:25. The two-pane panorama (Figure 4, 0:53) seems to fit the cloud area completely.

Stir. Night clouds between north and northeast. Edit The sky was almost clear and clear. The light areas of the 0:09 second image stood out and the editing confirmed. Based on the 0:23 panorama, the presentation is not quite small but not 1/8 scale nonetheless. At one time, in the narrow view of the window to the north, a dim belt was visible at a height of about 7 degrees.

There was a promising haze in the sky but no attempt at it, yet about half of the summer dwarf was visible for a while.

Excellent weather, dull slender belts in the north-northeast. Edit. While editing the pictures, a few streaks were found a little earlier 23:34 -> 23:22. I added another panorama at 23:54. There is that background sky quite bright from the north in the direction of the north.

22r first stood out only as an arc resembling a delicate cloud-skinned clear sky. Within minutes, colors appeared on the arc, and in about half an hour it faded away.

Primary rainbow

The very juicy head of the main rainbow glowed for a moment. There was interference. Because of the clouds, the red edge of the bright part looked fun bulging.

A pretty evening halo was visible for a quarter. The little cloud of color also wanted to be included in the picture.

Aurora rays

Pentti Arpalahti

There were several bright nights in a row, but even weak repos couldn’t be caught, even though the Z component dropped promisingly. In the end, you ripped. In the first picture, there was a swirl of smoke, which I zoomed into the second picture, perhaps left by the wind. Even a few rays flickered funny at the street lamp. There are additional reddish reflections on the left side of the left street lamp.
