Moon

Jarkko Alatalo, Ursa (Pohjois-Suomi)

Month about 99%. At the same time, an owl was heard from the south direction. A great moment in the light of the moon.

Several halo forms

Jarkko Alatalo, Ursa (Pohjois-Suomi)

Well now it was a short 22. And it never took more than a few minutes.

Active aurora band

27.8.2021 at 23.34 - 01.04 - Raahe (III)
Jarkko Alatalo, Ursa (Pohjois-Suomi)

I didn't go out a little sooner, but the curls looked like I had to go and watch. I left walking towards the edge of the field. During the trip, the eyes got used to the dark and coming from the middle of the forest to the edge of the field, nice-looking northern lights were visible (Fig.1). I continued my journey to the next field opening. The moon illuminated the landscape and in the background on the horizon the lights of the Raahe steel plant reflect (Fig.2). I settled in the same place where I made this summer’s NLC observations. The active arc rose one after the other, slightly brigh...

Hyvin heikkoja yöpilviä

Jarkko Alatalo, Ursa (Pohjois-Suomi)

Weak night clouds in the northern sky. By observing, one could barely guess whether it was. The pictures show a little more clearly. The view when I left was the first picture, when it was the darkest moment of the night.

Bright night shining clouds

13.8.2021 at 00.35 - 02.05 - Raahe (IV)
Jarkko Alatalo, Ursa (Pohjois-Suomi)

Stir! Low below 10 degrees in the light northern sky. I almost gave up, but as the dark cloud receded, a nice-looking shape began to appear. That dark cloud was in the northern sky all the way early, slowly flying east. In the beginning, it covered a much larger area. Otherwise, almost clear. Pretty soon after the initial situation, they became clear as a fine observation. Almost as quickly began to fade. By 2 p.m., it had clearly waned. I estimate the altitude to be a little over 10 degrees and the direction from north to northeast. Other sightings of the night included at least a few starbur...

Negative observation of missing night shining clouds

8.8.2021 at 00.00 - 01.50 - Raahe
Jarkko Alatalo, Ursa (Pohjois-Suomi)

Observation condition good. Clear, light breeze. Even the temperature is well over 10 degrees. On a couple of occasions I had to rattle my ears to hear correctly. Just like a grasshopper chirping :) Photo taken at 1.28 (sun -9.3)

Rare clouds

7.8.2021 at 00.59 - 01.45 - Raahe (I)
Jarkko Alatalo, Ursa (Pohjois-Suomi)

In the perfectly clear sky as the creeps appeared only the barely visible night clouds. Even in the pictures, it looks like just that. The slightest cloudy weather would not be able to identify, with such a clear sky and visibility of the time as well as how they began to appear so dare to put as an observation. In a large picture one cannot see correctly, but if one imagines correctly then one can see green. As a bonus Jupiter and a couple of months :) Main picture taken at 1.24, sun -9.0 (next night when this limit is broken this season)

Dim night shining clouds

6.8.2021 at 00.45 - 02.50 - Raahe (II)
Jarkko Alatalo, Ursa (Pohjois-Suomi)

Shortly before that, dim threads began to take shape in the northwest. Shortly after that in the northeast and north. As the crescent moon rose behind the forest in the same direction, it was perhaps the most visible but small area of the night. I chatted before three and then was still in sight, but already less visible. Picture 1) at 1.47 a.m. sun -8.6 (northeast) Figure 2) at 0.52 sun -8.5 (northwest) Picture 3) at 1.03 sun -8.6 (Northeast) Figure 4) 1:24 a.m. sun -8.7 (northeast) Figure 5) at 1.31 sun -8.7 (north) Figure 6) at 1.45 a.m. sun -8.7 (northwest) Figure 7) at 1.58 sun -8.5 (nort...

Dim night shining clouds

4.8.2021 at 00.30 - 01.50 - Raahe (II)
Jarkko Alatalo, Ursa (Pohjois-Suomi)

What a difficult observation night. Right from the start, I saw threads that stretched all the way to the law of heaven. I put the camera on a tripod to take pictures every minute from 0.42 to 1.17. I looked in between how they developed. In the end, I ended up not even having night clouds when photographed every minute, the movement was so clear. In fact, when there is such an impression that in the past the movement would have been almost imperceptible in such a short time. Figures 3-7 are that starting set. 3-6 images directly from the camera. After all, they look like night clouds, but the...

Negative observation of missing night shining clouds

1.8.2021 at 00.00 - 01.40 - Raahe
Jarkko Alatalo, Ursa (Pohjois-Suomi)

I mark the first observation of the summer as negative. The time of taking the picture was 1.25 pm when the height of the sun was about -7.41. At the start of the day -5.65. Throughout the observation period, there was no sign of night clouds and there could not have been a much better observation condition.

At least 10 lightning strikes seen

22.6.2021 at 15.15 - 16.00 - Raahe
Jarkko Alatalo, Ursa (Pohjois-Suomi)

The picture was taken at 3.15 pm in the direction of the thunder front. I followed the thunder inside. I calculated the flashes seen from the living room window. A total of 40 flashes. A few nice flashes. The nearest ones hit something less than two miles away. Looking at the radar pictures, you can see that the best storm did not hit but went from the southeast

Partial solar eclipse

10.6.2021 at 12.50 - 15.16 - Raahe (IV)
Jarkko Alatalo, Ursa (Pohjois-Suomi)

The morning went on a day butterfly excursion. I just got started and got the cameras ready. Shortly before the maximum, the fine thunderstorm itself became a little distracting. Timelapsek also got a little shot because of the cloud. However, I will put a couple of pictures of it too. The sky became clear from the direction of the sun shortly before the end. Figure 1. at 13.43 Figure 2. at 12.50 Figure 3. at 14.05 Figure 4. at 1.49 p.m. Figure 5. at 13.41

Day butterfly monitoring in the nearby swamp. Butterflies a little on the fly, but there was still a halo and a handsome bark that left a sore memory behind my ear.

While flying in the yard with Makro, the fighter flew over and the gaze turned to the halo :)
