Clearly visible night shining clouds

9.8.2022 at 23.15 - 00.45 - Vantaa (III)
Paula Wirtanen, Anne Wirtanen, Ursa (Helsinki)

A quarter past eleven, Anne Wirtanen suspected that she would see illuminating night clouds in Myyrmäki. They were still quite dim, but I recognized them from the photo (photo 1): that's them! So I went myself to the actual observation site to wait and the sight was quite beautiful considering the time, the illuminating night clouds were quite bright and still quite high in the sky. Yes, these were worth admiring (pictures 2 and 3). I myself returned to the observation site after midnight. Now, like the end of the season, the night clouds were visible quite low (approx. five degrees). What...

Dim night shining clouds

6.8.2022 at 00.10 - 01.00 - Vantaa, Pähkinärinne (II)
Paula Wirtanen, Anne Wirtanen, Ursa (Helsinki)

Very dim illuminating night clouds, almost like cloud streaks at a quick glance. However, they stood out clearly when you knew how to look. I went to check the situation a little after the turn of the day and then nothing was visible in the sky, the weather was partly cloudy. A little later I got an alert that there might be something to the north. So a quick return to the observation point on the top floor platform and yes, there was a dim night cloud there low down right next to the horizon. Pentti Arpalahti , in his own observation from the same period, has estimated the height to be five d...

Eye-catching night shining clouds

28.7.2022 at 23.30 - 00.00 - Vantaa, Pähkinärinne (V)
Paula Wirtanen, Anne Wirtanen, Ursa (Helsinki)

After 23:00 there was a clear, bright belt in the northern direction: night cloud? Time the brightest? At 23:30 it was already very easy to recognize it: among the dark, reddish clouds, a very well-illuminated and electric-blue illuminating night cloud stood out. Quite a beautiful, nice and bright night cloud show, the kind you can expect at the end of July.

Primary rainbow

27.7.2022 at 21.40 - 21.50 - Helsinki (IV)
Anne Wirtanen, Ursa (Helsinki)

A bright and handsome rainbow admired from the connection terminal in Malmi while waiting for the bus. The rainbow could be seen as a complete arc, the right edge was only hidden behind the house (picture 1). Also the lateral rainbow and the Alexander dark belt between them became clearly visible (pictures 2 and 3). The colors of the rainbow were very clear and bright.

Hail in the summer season

17.7.2022 at 13.35 - 13.45 - Vantaa, Pähkinärinne
Anne Wirtanen, Ursa (Helsinki)

There started to be quite a crackling sound, well, hail was coming from there. The hailstorm lasted maybe ten minutes, it rained both water and hail. In the video, you can see and hear the bouncing of the hailstones. Shot through the kitchen window.

Primary rainbow

13.5.2022 at 19.55 - 20.05 - Helsinki, Tuomarinkylä (V)
Anne Wirtanen, Ursa (Helsinki)

A full and bright pair of rainbows was seen in the rather heavy rain. Photographed from a bus window on a mobile phone, which is not a very beautiful series of photographs, but yes you can get an idea of both the rain and the arch. It looked great really. Alexander's dark belt also stood out easily.

Moon

4.5.2022 at 21.50 - Vantaa, Pähkinärinne
Anne Wirtanen, Ursa (Helsinki)

May the 4th be with You! The crescent hunt started pretty badly in May due to the weather, but now a fine crescent moon was finally smashing in the clear and light sky. About 14% of the moon was illuminated and the moon was just under four days old.

Moon

3.4.2022 at 21.08 - Vantaa
Anne Wirtanen, Ursa (Helsinki)

Narrow crescent moon falling. Thin cloud bullying. The country house was not separated, there is a slight hint of it in the picture.

Lunar corona

9.3.2022 at 19.25 - 20.10 - Vantaa, Pähkinärinne (III)
Paula Wirtanen, Anne Wirtanen, Ursa (Helsinki)

The circle visible around the moon at times teased the observation of the Moon itself. After eight in the evening, it thickened somewhat and affected transparency. The second picture also includes Aldebaran. No other stars in the area were visible to the naked eye.

Moon

18.2.2022 at 22.57 - Vantaa, Pähkinärinne (IV)
Anne Wirtanen, Ursa (Helsinki)

The moon photographed from the backyard. I grabbed a picture with a SLR camera for a while, waiting for the telescope to get a glimpse of the Moon. Luck shot.

Lunar corona

12.2.2022 at 19.50 - 20.00 - Vantaa, Pähkinärinne (III)
Paula Wirtanen, Anne Wirtanen, Ursa (Helsinki)

Quite a small perimeter, some fog in the air. Colors Va / P, dimmer colors.

Lunar corona

16.12.2021 at 18.00 - 18.15 - Vantaa, Pähkinärinne (III)
Paula Wirtanen, Anne Wirtanen, Ursa (Helsinki)

Through the gloomy clouds, the Moon parted for a moment. The perimeter was clearly seen, the colors Va-KOP, from which the orange hue stood out most easily. Quite a normal perimeter that at times was not visible at all after the Moon was behind the cloud. The clouds moved quickly and over time the moon covered behind the cloud. The weather will be almost completely cloudy, possibly clearing up.

Lunar corona

18.11.2021 at 22.15 - 22.50 - Vantaa, Pähkinärinne (IV)
Paula Wirtanen, Anne Wirtanen, Ursa (Helsinki)

It was a firm intention to admire the Moon and explore the magnificent splendor of the full moon with a telescope. Almost remained a company, Cloudy when more or less a nuisance all the time. However, the perimeter of the moon was fine. The perimeter was at its best at 22.15-22.30, after which the Cloud Cover began to thicken. The cloudboards moved fast. At times, the radius of the perimeter was only half a degree and it was almost colorless. The most handsome colors were with a bluish Va / KO radius of perhaps a couple of degrees (the image can be accurately measured). Yes, the moon was somew...

Other storm phenomenon

12.8.2021 at 11.40 - 12.15 - Vantaa, Pähkinärinne
Anne Wirtanen, Paula Wirtanen, Ursa (Helsinki)

A distant rumble began to sound and then a flash flashed. Thunder! Not yet, but a severe thunderstorm did come to the area. Or a few flashes (less than 5) were observed, but there was a strong rumble. Then a downpour that lasted violently for half an hour. And from this an observation of flooding rain. There was water up to his ankles outside.

Eye-catching night shining clouds

1.8.2021 at 23.45 - 00.15 - Vantaa, Pähkinärinne (V)
Anne Wirtanen, Ursa (Helsinki)

I got excited to go on a night cloud observation trip, when they were already quite visible from the window and the show had started. I'm not out to describe.

Clearly visible night shining clouds

29.7.2021 at 23.20 - 23.50 - Vantaa, Pähkinärinne (III)
Paula Wirtanen, Anne Wirtanen, Ursa (Helsinki)

Anne Wirtanen peeked out the window and noticed that there were possibly illuminating night clouds in the sky. Well, they are! At the same time, I even got a fuss about it. The biggest problem with the observation conditions was partly cloudy air. There were large conventional clouds on the horizon in particular, and this too could easily have been acknowledged as such. But the illuminating night cloud it was, it was revealed not only by the texture but also by the color and the transformation of a pearl. Based on the photo, the case is also quite clear. We watched the sky for about half an ho...

Hyvin heikkoja yöpilviä

25.7.2021 at 02.30 - Vantaa, Pähkinärinne (I)
Paula Wirtanen, Anne Wirtanen, Ursa (Helsinki)

After the negative observation, we were already pretty sure it would be here for the night. What else! By half past one, Anne was still peeking out the window and noticing a dim belt visible in the sky. One picture and sleep. It was a bit blurry. The night clouds came quite late and were quite dim for a short period of observation. So here in the sky clouds appeared between two and a half to three.

Moon

25.7.2021 at 01.37 - Vantaa, Lammaslammen ranta (V)
Paula Wirtanen, Anne Wirtanen, Ursa (Helsinki)

It all started when at one time at night we saw the Moon ushering inside the living room window. That's where you get the picture! The moon was quite low and in the backyard it was visible behind the trees: to take a photo I had to go a little further. The shore of the sheep pond was atmospheric. The moon was low, Jupiter stood out bright from the already quite dark sky, and Saturn also stood out near the moon's glow in one direction. The telescope was not included in the trip this time. During the same walk, one could also observe possible night clouds (separate observations from thes...

Negative observation of missing night shining clouds

25.7.2021 at 01.00 - 02.00 - Vantaa, Pähkinärinne
Paula Wirtanen, Anne Wirtanen, Ursa (Helsinki)

An hour of adventure in the immediate area, not just seeing any kind of night clouds. Two images from the end of the observation period. Half an hour later, a night cloud appeared, a separate observation from it.

Bright night shining clouds

13.7.2021 at 00.00 - 00.40 - Vantaa, Pähkinärinne (IV)
Paula Wirtanen, Anne Wirtanen, Ursa (Helsinki)

A peek out the window shortly before midnight, when nothing was visible in the sky yet. But at midnight the countries in the north were already clearly beginning to show quite bright night clouds. So the familiar tour through the upstairs window to the yard journey began. The play was at its most handsome in a northerly direction, at its best the night cloud reached about the zenith. There was no visibility to the south. Figures 1 and 2: Northwest Sky. The night clouds are brightening to the north. Figure 3: In the west (the visible star is Arcturus) there is starting to be just an ordinary cl...
