Leaving Stockholm, the bright sails danced on the edges of 22r. ZYK mocked, but disappeared immediately.

A few minutes ago, 22r and the left side sun stood out in Tammisto, Vantaa.

One halo form

27.3.2021 at 17.34 - 17.45 - Vantaa (I)
Pentti Arpalahti

For a total of ten minutes, a pillar was visible below the Sun, and finally another spot of light as the Sun sank behind the clouds. The shade of the sky was strangely cloudy yellowish. I put the pillar in the cloud cloud account or if it was of anomalous origin.

Aurora rays

3.9.2016 at 23.37 - 23.47 - Uppsala, Ruotsi (II)
Pentti Arpalahti

In Uppsala, on the shores of Mälaren, the lighting of the streets and paths is moderate. In Graneberg, the stars stood northwest almost to the horizon. A pontoon pier has been built on the waterline through the reedbed, from which I was able to photograph part of the dim arc and a few radii. I spelled the observation time according to Finnish local time.

Several halo forms

24.5.2015 at 12.26 - 19.12 - Uppsala, Ruotsi (II)
Pentti Arpalahti

12.26 - 12.38: There was a flat gauze in the sky, from which a fairly clear 22r stood out. It soon appeared as a cloudy strip about 60 degrees from the horizon ring, which already stood out well from the pictures. The show ended in ten minutes as the ferry of ordinary clouds flew forward from the west. Edit. 18.58 - 19.12 there was another show in the play. There was a zyk and a 46 degree upside down - I guess it is when you are stuck in a zyk and colored. The trip didn’t come with a full toolkit for handling, so I had to improvise a bit. I recorded the observation times according to Finnish t...

Clearly visible night shining clouds

8.7.2014 at 01.01 - 02.30 - Uppsala, Ruotsi (III)
Pentti Arpalahti

Visually visible two thin belts in the north at five and ten degrees at one time, but the play stumbled considerably by two. 2.30 clouds have already risen to 60 degrees, but now it is necessary to go to sleep. Lumia flap as a sample. More pictures later. Simultaneous observation from Finland would be nice. I set the observation time according to Finland.

Negative observation of missing night shining clouds

24.5.2015 at 00.00 - 00.20 - Uppsala, Ruotsi
Pentti Arpalahti

There were no illuminating night clouds in Uppsala either, but the visa victory still came there. I recorded the observation time according to Finnish time. The conditions seemed promising at first, but at about 0.15 clouds began to accumulate in the sky and in half an hour the sky completely faded.

Dim night shining clouds

12.6.2016 at 01.35 - 02.05 - Uppsala, Ruotsi (II)
Pentti Arpalahti

In Uppsala, a good group of night dwellers was seen in good conditions. I wrote the observation according to Finnish time. At 1:35 a.m., the clouds were clearly visible through the window. Local time from one the clouds were already fading from view in the morning sun.

Other special clouds

25.12.2016 at 13.45 - Uppsala, Ruotsi (III)
Pentti Arpalahti

I don't have time to take a few pictures of a cloud hole with an intact edge. Planes departing north from Arlanda fly in this direction. I left the maintenance to be condemned,

The view from the northern tip of Mälaren opened up in a low-light pollution direction, where even the dimmer areas of the Milky Way were distinguished in good conditions by a single exposure. I recorded the shooting time according to the Swedish time.

Primary rainbow

As the sun went down, a pretty piece of the rainbow appeared. The square image is in the direction of the sunset. The vivid image has the last creep of the arc. I spelled the observation time according to Swedish time. EXIFs are in Finnish time.

Quiet aurora arc

7.11.2015 at 19.36 - 20.12 - Uppsala, Graneberg, Ruotsi (II)
Pentti Arpalahti

The dim little performance in Uppsala was a consolation when attempts to detect the Korona opening eruptions of previous days failed. I recorded the observation time according to Finnish time.

Aurora rays

12.9.2014 at 23.00 - 23.50 - Uppsala (II)
Pentti Arpalahti

The observation site was the edge of the sports field south of Uppsala. No tripod was then found in the foreign place, but at the edge of the field in the wound trunk a knot stuck out appropriately to provide enough support for the five-second exposure. The dim light in the north was first suspected to be the center lights, but the camera screen showed the color green and the dim arc gradually rose higher. The first splash convinced the fires to break out and I dared to invite more spectators to the scene. That's why the ray show started and one of the viewers got to see their first repos....

One halo form

Pentti Arpalahti

The dim 22r was visible for a while. The channel mix turned black and white briskly into red and a little green, and adding blue brought out the ring more and better, even though the raw image was just a cell phone jpg. Observation time according to Finnish time.

Vihreä reuna

4.5.2017 at 21.47 - Tukholman ulkosaaristo, Ruotsi
Pentti Arpalahti

I tried to catch a green glimpse, but the boat had not made it from the Stockholm archipelago to the open waters, so there were still terrain obstacles on the horizon. A rather marginal border greening in the images may be distinguished. I took the last four pictures every three seconds. The color temperature is the camera's sunlight setting (LR indicates 5200 K). The first image is a magnification of the weave image. The time of the observation is Finnish summer time.
