ISS

28.10.2021 at 06.35 - 06.40 - Helsinki (IV)
Georg Kieninger

After a period of cloudiness that seemed like an eternity, the sky opened this morning and the passage of the ISS could finally be well described. Direction of travel SSW-SSE-SE, magnitude -1.3. The image is a stack of 221 squares.

Quiet aurora arc

19.10.2021 at 00.54 - 02.42 - Helsinki (II)
Georg Kieninger

At the beginning of the episode, the northern lights were visible from the cloud (Fig. 1), at 01.56 onwards as a weak but permanent and moving arc, there were sometimes a few rays (Fig. 2 and a video / Fig. 3 composed of about 40 squares)

Quiet aurora arc

17.10.2021 at 21.47 - 02.26 - Helsinki (II)
Georg Kieninger

Cloud cover ranged from cloudless to covered. In any case, the periods were so bright or cloudy that the northern lights came out quite comfortably. Figure 1 is from the beginning of the episode, Figure 2 from its best phase at about 1.25-1.48 and Figure 3 from the phase when the Cloud Cover began to close. Figure 4 is a video compilation of about 170 frames from 21.47-02.26.

Aurora rays

30.9.2021 at 23.31 - 23.37 - Helsinki (II)
Georg Kieninger

There were enough openings in the cloud cover that the northern lights were visible for even a few minutes. The picture captures the best moment of that short episode.

Rocket-related clouds

28.9.2021 at 00.12 - 00.15 - Helsinki (IV)
Georg Kieninger

The camera was set to continuous shooting mode to capture any northern lights that might appear. They did not come, but the four images had a rocket launch reported in numerous other observations. The attached image is therefore a stack of four images. The rocket seemed to come from the west and pass northeast - pictured from left edge to center down to right, for the fourth time it appears dimmer behind the crane lifting hook wire. #raketti: Centaur V #satelliitti: Landsat 9

ISS

27.9.2021 at 19.43 - 19.48 - Helsinki (IV)

ISS crossing photographed in Kaivopuisto. A stack of about 70 squares. It was still very bright, all the colors of the landscape stand out clearly. The beginning of the ISS trajectory, on the other hand, stands out rather weakly.

ISS

Georg Kieninger

The passage of the ISS, which was filmed last Sunday in two different places (Hernesaari and Eläintarhanlahti) and appeared quite clearly. In the picture of Hernesaari (picture 1), the rel. clearly four other satellites (3 on the far left, 1 in the middle of the picture) which ones I had no idea. The image of the zoo bay shows - albeit very weakly - only one additional satellite running from the upper left corner down to the right. The Great Church and the tower of the National Museum also stand out in the picture. A glaringly bright horizontal line of light on the right was created by the lig...

4-pronged Kelvin-Helmholtz line in the cloud hole, Helsinki's Hiatalahti. At first I thought / hoped that there would be more of them, but on the contrary (Figure 2), they disintegrated very quickly.

ISS

9.9.2021 at 04.44 - 04.49 - Berliini, Saksa (IV)
Georg Kieninger

The ISS crossing in Berlin, pictured also the Federal Chancellery (light building on the right) and the Reichstag (federal parliament building - dome in the middle of the picture and the annexes to the federal parliament in the picture on the left). The image consists of a total of 198 frames and is a panorama assembled from two stacks of images, which is manually a bit clumsy. For this reason, the flight path looks a bit uneven. Highest point 46 degrees, direction of travel WSW-SSW-SE, magnitude -3.5. 9/20/2021: Image changed because there was a quality error in a previously uploaded image

ISS

8.9.2021 at 05.30 - 05.35 - Berliini, Saksa (IV)
Georg Kieninger

As an avid Skywarden tourist, I couldn’t fail to photograph the Funkturm attraction along with the ISS. Direction of travel W-SSW-SE, highest point 36 degrees, magnitude -3.0. I didn’t even get to photograph the entire flight path, in the west (pictured right) part was left out of the picture. A stack of 134 squares. Funkturm was built in 1926 as a radio mast.

ISS

Georg Kieninger

The ISS crossing of the International Space Station photographed at the Brandenburg Gate (Brandenburger Tor). In addition to me, the event was followed by a city fox, which I did not get photographed, however.

Georg Kieninger

Another ISS crossing over Berlin the same morning. The scene this time is a roundabout called Grosser Stern, in the middle is a 67 m high monument called Siegessäule. The highest crossing point is 59 degrees, magnitude -3.5, direction W-SSW-ESE. Stack of 228 squares.

Crossing of the brightly visible International Space Station over the Reichstag (Federal Day Building), one of Berlin's landmark buildings, direction E-ESE. The picture also shows the TV tower (red lights on top) and the Bundestag annex (just left). Stack of 125 squares.

Weaving in front of Helsinki 9/20/2021 corrected time of observation. The first time reported was the time the collage was made.

Moon

19.8.2021 at 22.54 - Helsinki (IV)
Georg Kieninger

Surprisingly, the sky became clearer and the Moon, which grew by almost 87 percent, shone between the clouds. The second image is a composite image: with normal exposure, the Moon would only appear as a bright bright dial. That’s why I stacked two images - a deliberately less exposed number one image with the Moon’s dark spots and craters clearly visible, and an image where the exposure mostly highlighted the clouds. In this way, the human eye sees the situation, that is, it corrects the "overexposure" of the Moon; the camera can only illuminate according to either the clouds or the bright moo...

Primary rainbow

19.8.2021 at 19.39 - 19.50 - Helsinki (IV)
Georg Kieninger

I thought it would look like a rainbow would appear. And no matter what, that's where it appeared, whole and in the end, the right foot of the side rainbow also came along. In the first and second picture, the foot of the rainbow is on Kuivasaari. Figure 3 shows the rainbow in its entirety.

Perseids

13.8.2021 at 00.18 - 03.04 - Helsinki (IV)
Georg Kieninger

The cloudless sky comfortably happened to the maximum night of Perseids. The images included a lot of satellites, which, however, differed well from the asses when the same satellite was in several consecutive images and the streak they generated looks different. So here are just asses.

A short-lived but handsome main rainbow. Just to the right you can see the base of the side rainbow.
