Dim night shining clouds

29.6.2022 at 01.03 - 01.18 - Laivareitti Maarianhamina - Helsinki (II)
Pentti Arpalahti

I thought at one time it would be optimal to go check the night clouds. On the deck of the boat, the wind blows so that even the last hair flies away. It was warm and foggy. The faint line stood out 1:03 just fine on the edge of the brown zone to the north. There was a bit of a curve, like a wave, resembling KH. At their widest, the belts were 1:05, to the northeast there were some lines. Then they were already gone, the last picture 1:18.

We got on a long night shooting trip. Sunsets were described and post-sunset color reflections in lakes and bays. Afterwards, I only realized that there were very weak illuminating night clouds. The colors caught my attention when shooting. It was a hot, beautiful night.

In the beginning, the area covered by the night clouds was indeed small, but it expanded and then moved all the time, still remaining strictly to the north. Figure 1 was taken at 1:20 a.m. when the area was at its widest. Figure 2 is a timelapse of approximately 90 frames over the entire observation period. Edit: corrected observation time (00.40 instead of 00.14)

I woke up after two and went to check if anything was visible in the sky, there were clear night clouds heading north.

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.

Alarm type, something in the north. Considering the light, quite moderately visible. Quick rap on a cell phone.

With the naked eye I imagined seeing something miscellaneous in the northwest, since then I no longer saw that trace. In the situation of observation, it was difficult to say at all whether or not there might be a night cloud there. In the end, I came to the conclusion that that night cloud might not be, but just because of the twilight rays, I took a photo of the area for sure. However, when examining and processing the photograph, it appears that there is a very delicate and dim belt illuminating the night cloud, which looks quite similar to the observations made by others from the same dire...

The camera captures dim illuminated night clouds from the twilight rays. Attached is a sample of roughly the best (least weak) moment (1.32) in the standard and USM versions. From the USMatted version of the timelapset recording, I estimate the cloud time to be about 1.00-2.30.

About a quarter of this was a small and dim night cloud area with the naked eye a little from north to northwest. Both images also in confidence.

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.

It started moving from the east and the zenith before midnight. These night clouds seemed a little “lighter” than the night clouds in early summer in general. These did not shine so brightly, but there were nights in every direction of the air. Very nice show. And true, as the night progressed, the shapes and glorifications in the sky changed quite frequently and were everywhere. Again, a tense, cluster-like night cloud shape appeared. I immediately looked at the radars of the rain and cloud areas on the spot, and I did not detect the usual cloud fiber or rain area on the radar in the directio...

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.

Thanks to Pentti Arpalahti's alarm, I will be able to show this time. Here in the city center, I thought the night clouds were only dim, but still stood out well visually. Moved from north to northwest. Location Hietalahti. Also included is a timelapse of about 50 squares.

I was watering the Tuija fence in anticipation of hot days when I noticed a horseshoe-like hole in the cloud curtain in the sky and vulgar shapes inside it. At the same time, it began to resound that this revelation, although it is in that shape, must be a cloud of holes. So I immediately put my cell phone camera to sing.

Mikko Peussa got tips from the illuminators before one. I set out to check on the situation, but the raspberry wool spin on the porch made the check-in forget for a moment. And those clouds hadn't escaped anywhere in a few minutes. To the north, a faint or perhaps even clearly visible group of waves was visible. First image a little later (1.26) moderately processed, second image (1.07) USM-assisted. The treatment brought out even a denser wave and a bundle of twilight rays.

The illuminating night clouds first began to appear between the north and the northeast. The focus then shifted north and finally the show began to fade even before the darkest moment of the night.

Veikko Mäkelä put a message in the middle of the night clouds in one of the countries, something would be visible in the northern direction. I was just going to see the sky of Midsummer myself, and quite accurately I was able to giggle clouds that still stand out quite poorly. I could see a wave-like formation, however, then began to stand out with clear belts, albeit a little hazy. Without a quarter, however, these began to brighten and were already quite noticeable. Belts, slightly wavy and gauze. And Capella, which can be seen in the pictures, stood out from the sky of Midsummer with the na...

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.

At one time I looked at what was visible in the night sky and there was a small area of night clouds, this one about southeast.

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.
