Quiet aurora arc

21.3.2023 at 23.30 - 03.30 - Kurikka, Jurva (II)
Timo Nevala, Ursa (Länsi-Suomi)

Update from the night before , the picture is almost the same. Although the northern lights were visible for longer now, and on the other hand, there were more clouds ahead, and I can't say for sure if the arc that was low was at some point from calm to perhaps more restless. In addition to the northern lights, I followed the space weather of the Finnish Meteorological Institute. At the measuring stations in the south, the magnetic activity did not fluctuate much above zero, and the "humps" were not red even in Lapland. Nevertheless, the sky was green with the northern lights. And it wasn&...

Quiet aurora arc

21.3.2023 at 01.45 - 02.05 - Kurikka, Jurva (II)
Timo Nevala, Ursa (Länsi-Suomi)

I saw the aurora arc low in the north, but it started to fade before I could get the camera. The gauze above the arch was so dim that its color could not be seen with the naked eye, but in the photographs it was purple, and not green as often. The orange shapes in the picture near the horizon are clouds colored by light pollution. Compared to last week's northern lights show, tonight's northern lights were nothing...

All-sky aurora

15.3.2023 at 23.40 - 01.40 - Kurikka, Jurva (IV)
Timo Nevala, Ursa (Länsi-Suomi)

The northern lights were able to surprise. I went to the yard to see if the artificial light pillars from earlier in the evening could still be seen, but there the Northern Lights show was about to start! And it was great. I followed the display until it started to fade away and the winds would dip back towards the north. The pictures try to tell what kind of views were available. There was a lot of red, especially in the photos, but you could distinguish it with your eyes. The corona wasn't terribly impressive. The shape in picture 2 looks like a picket fence, but I'm not sure if that...

Light pillars

15.3.2023 at 21.30 - 22.00 - Kurikka, Jurva (II)
Timo Nevala, Ursa (Länsi-Suomi)

I was a little startled when I went to the yard and noticed a green ray of light coming from behind the forest. It wasn't very bright, but in a direction where I know there are ten or so kilometers of uninhabited forest without any mentionable roads. My first thought was that it was the aurora borealis, but since it stayed as it was, and there were no aurora borealis visible anywhere else, I concluded that it was an artificial light pillar. (Later at night, though, we could see the northern lights as well.) I took a few pictures of the green pillar, and noted that there was also another, r...

One halo form

13.3.2023 at 14.15 - Kurikka, Jurva (I)
Timo Nevala, Ursa (Länsi-Suomi)

I think I also saw a bit of the 46° ring above the 22° ring, but it was very, very dim. So dim that it was no longer visible in the photos. And I couldn't force it out of the pictures believably, even with the power of harsh image processing. I only check the 22° tire, because the 46° case was a bit uncertain.

Several halo forms

8.3.2023 at 22.00 - 02.00 - Kurikka, Jurva (II)
Timo Nevala, Ursa (Länsi-Suomi)

This observation is a continuation of the observation of "durational halos" . That is, the same halo continued in the evening under the power of the Moon, which had been the case with the Sun during the day and the previous night with the Moon . The halo shapes were otherwise the same, except that the Moon could no longer see all the ones that the Sun could. The moon also had a side sun tonight - I'd rather call it a side moon. I already thought that this was becoming a permanent situation, but at night the halos started to dim. In about two countries, you could say that they were no longe...

Several halo forms

8.3.2023 at 10.45 - 17.45 - Kurikka, Jurva (II)
Timo Nevala, Ursa (Länsi-Suomi)

Now there are real permanent halos in the sky! Halotus started in the evening of 7.3. when the full moon rises, and it's still going on as I write this in the evening of March 8th, it's already been over a day. A 22° tire and a clear upper side opening have mainly been offered, but other shapes have sometimes stood out quite nicely. The light source has changed from the Moon to the Sun and back again, so I assume that night and day halos must be reported separately. The same upper cloud there in the sky has obviously been there all along, because the halos have been pretty much the sam...

Several halo forms

7.3.2023 at 20.00 - 04.00 - Kurikka, Jurva (II)
Timo Nevala, Ursa (Länsi-Suomi)

This is where the "lasting halos" really started. A 22° ring was visible above the moon and the upper side opening with variable brightness for however long. I assume that the halos were visible continuously even after the recorded time, because the next morning similar halos were then visible above the Sun. And in Sunlight, other halo forms emerged. In addition, the halos continued the next night as well. This first night observation can only be represented by one picture. I took several others, but in the end they were all so similar to each other. Apart from the change in brightness, nothin...

One halo form

6.3.2023 at 23.20 - 23.45 - Kurikka, Jurva (I)
Timo Nevala, Ursa (Länsi-Suomi)

A colorful nocturnal halo above the Moon was only visible for a short time. Maybe it's better that way, because in almost 20 degrees below zero, I wouldn't have liked to follow it for very long.

Timo Nevala, Ursa (Länsi-Suomi)

For a while, a reasonably bright 22° ring was visible on the moon. The above-mentioned opening was also included. The ring was not perfect: the lower part was missing.

Venus and Jupiter

2.3.2023 at 18.42 - Kurikka, Jurva (II)
Timo Nevala, Ursa (Länsi-Suomi)

That meeting of the planets was a bit of an unreal-looking event. It was as if Jupiter was hanging on to Venus by some invisible ropes, and Venus was dragging the planet with it somewhere.

All-sky aurora

27.2.2023 at 19.30 - 23.30 - Kurikka, Jurva (III)
Timo Nevala, Ursa (Länsi-Suomi)

Last night's northern lights show still continued. The fires began to appear as the sky darkened. The best, most colorful pieces were served right away, after which the sky clouded over. Later, the cloud cover opened for a while, revealing greenish belts, until before midnight it was no longer possible to distinguish the aurora borealis through the cloudiness. Overall, this was more modest than last night's show.

All-sky aurora

27.2.2023 at 01.30 - 03.00 - Kurikka, Jurva (IV)
Timo Nevala, Ursa (Länsi-Suomi)

The sky became cloudy even before the northern lights show could even begin. I always went to the yard to check the situation, but it wasn't until half past two that the cloud cover seemed to be thinning and tearing a bit. That's when you saw how the aurora borealis was everywhere in the sky. Quite bright, apparently, because it was visible even through the thinning clouds. An interesting detail was a bright ray that suddenly "shot" from the north towards the zenith, but dimmed so quickly that I couldn't get a good picture of it. Soon after, the sky clouded over again. After a brea...

Diffuse glow

25.2.2023 at 20.45 - 22.30 - Kurikka, Jurva (I)
Timo Nevala, Ursa (Länsi-Suomi)

At some point during the evening, an aurora borealis had appeared in the sky. It was in a bigger field today than the day before . At its best, roughly a quarter of the sky glowed green and the gauze stretched all the way to Otava. Quite a reasonable performance here in the latitudes of Western Finland. Structures that look like arches and rays were also noticeable among the gauze, which, however, mostly stood out in the photographs. The sky clouded over at about half past eleven, and the sighting of the northern lights ended there.

Diffuse glow

23.2.2023 at 22.30 - 00.30 - Kurikka, Jurva (I)
Timo Nevala, Ursa (Länsi-Suomi)

Some kind of aurora activity was visible in the northern sky throughout the evening. Sometimes you could see a faint curve, sometimes gauze, somewhere in between you couldn't see anything at all. I always went to the yard from time to time to check the situation, but it wasn't cold there all the time, especially since the aurora never seemed to develop anything better. The picture was taken at 23:50 when the gauze was at its brightest (unless it was momentarily brighter just when I wasn't in the yard watching). NOTE: Only the green in the picture in the sky is from the northern lig...

Timo Nevala, Ursa (Länsi-Suomi)

I came across a faint pillar of sun when I went to the lake to see if there were any nacreous clouds. Well, there wasn't even a sign of pearls, and low clouds rolled in from the west to cover the view even before the sun even set. That pillar formed for a while in those clouds.

Pearl clouds

14.2.2023 at 17.00 - 18.30 - Kurikka, Jurva (II)
Timo Nevala, Ursa (Länsi-Suomi)

Fifth day of the pearl tube. You could see from the sky even before sunset that the pipeline would continue. The thick low clouds just pushed in front so that you couldn't see the pearls properly. But yes, they were there today too, the sharpened 2nd and 3rd pictures show it. After 6 p.m., the pearly brown glowed strikingly bright behind the low clouds, picture 1.

Landscape image of a planet

Timo Nevala, Ursa (Länsi-Suomi)

Venus (below) and Jupiter (above) are trying to compete in splendor with pearly clouds and pearly brown, but are still second at this point in the evening. This was filmed half by accident, when I was actually photographing pearls. A separate observation about pearls here .

Pearl clouds

Timo Nevala, Ursa (Länsi-Suomi)

Here is today's harvest of pearls. The pearl tube has been on for the fourth day already. This time, a few pastel-colored water ice pearls were also visible among the white acid pearls. The pearly brown was strong.

Pearl clouds

12.2.2023 at 17.30 - 18.30 - Kurikka, Jurva (II)
Timo Nevala, Ursa (Länsi-Suomi)

It was completely cloudy in the afternoon, so I thought that there would be no pearls to be seen today. But after the Sun had already set, there were gaps in the cloud cover, from which a very pearly cloud-like thing stood out in the background sky. I hadn't been able to prepare for this, and I didn't have time to go to any more spacious observation points. I tried to photograph pearls between the trees and the gaps in the low clouds, and it didn't work out very well. I'm not even entirely sure if the pictures showed pearly clouds or ordinary clouds. The second picture is like ...
