A fireball at night, brighter than the venus

27.9.2022 at 20.22 - Paimio (III)
Mika Aarnio, Turun Ursa

The star flight can be seen on 27.9.2022 at 20:22:27 in the time-stamped image on the left side (east).

Jupiter

19.9.2022 at 21.59 - Enontekiö (III)
Sakari Ekko, Turun Ursa

I took the picture on Tuesday 20.9. for a star-studded evening. Fittingly, the Galilean moons happened to be east of Jupiter in order of distance. On the night of the stars, we looked at Jupiter with my bird telescope, and the participants, seeing Jupiter's moons in nature for the first time, could tell that their positions had changed since the night before. There was also talk about Galileo and his importance in the history of science. We also looked at other things with the naked eye, binoculars and a telescope, but it seemed that Jupiter itself was the most memorable experience for the...

Half-sky auroras

20.9.2022 at 00.33 - 00.40 - Enontekiö (IV)
Sakari Ekko, Turun Ursa

My intention was to take a picture of the entire visible sky with the Milky Way visible across the sky to use on Tuesday 9/20. in the starry night, but the northern lights ruined my plans. On the other hand, I wasn't sorry. First, there was a bright arc across the sky through the zenith, and when I got to the shooting location and got the camera on the tripod, a handsome show began, which lasted only a couple of minutes. Then the green glow of the aurora borealis covered the sky in spots, and the clouds came quickly. Two of the series of half a dozen pictures were worth mentioning. The fis...

Sun

15.9.2022 at 10.00 - Nummenmäki, Turku (V)
Petrus Kurppa, Turun Ursa

In terms of the weather forecast, Turku was promised sunshine. The cheering up of a very gray and rainy day was an almost cloudless and harmless moment for shooting in the early morning. After noon, an avalanche of clouds has been almost a rule on several days. This year, the sun's chromosphere has reached its peak for the next few years. If there isn't something megalomaniacally big and impressive to see every day, there is always something small and beautiful on offer. I admit that for my part, these protuberances may be tolerated over time, and I always start to dig a little bigger,...

A fireball at night, brighter than the venus

12.9.2022 at 21.42 - Paimio, Kevolan observatorio (III)
Mika Aarnio, Turun Ursa

The shooting star visible in the images of the Kevola allsky camera of the Turku Ursa ry, the original images can be seen on the server of the Turku Ursa ry: https://turunursa.fi/allsky/images/20220912/image-20220912214204.jpg https://turunursa.fi/allsky/images/20220912/image-20220912214234.jpg The exposure times of the pictures are 29.75 seconds and the interval is 0.25 seconds. I made a combined image.

Pluto

25.8.2022 at 23.40 - 23.50 - Paimio (II)
Antti Parkkari, Turun Ursa

Clear weather up to the horizon enabled the attempt to photograph the dwarf planet Pluto. The Kevola tower's Planewave telescope found its location precisely. The biggest problem was finding a suitable search map. In the end, it was confirmed that it is indeed in the picture. At least this year, at a height of 4-5 degrees above the horizon, it was still possible to photograph Pluto,

8.9.2022 at 22.43 - Paimio (III)
Eeva-Kaisa Ahlamo, Turun Ursa

My heart is in Kevola, even though the weather forecast is full of clouds and almost a full moon. I went anyway. Clouds passed over several floors, but I shot timelapses and I used too Cloudy periods by browsing the internet for the news of Elizabeth II's passing. The star pictures actually turned out pretty great when the Moon lit up the clouds. Even the low clouds were moving very slowly, so the atmosphere in the moonlight was stagnant, but beautiful. I described the Milky Way between the clouds. The swan seemed to be flying between the night cumulus towards the south. Thus an era that l...

Auroras seen through breaks in the clouds

4.9.2022 at 22.40 - 23.20 - Turku (III)
Eeva-Kaisa Ahlamo, Turun Ursa

The attempt to photograph the northern lights in Turku was a bit challenging due to the cloud rafts attacking from the north. So yes, clouds and light pollution, just what you need at the time of the bright aurora borealis... (All stargazers can relate to this.) In the end, the clouds finally rolled in like Monday morning chores.

25.8.2022 at 12.00 - 15.00 - Nummenmäki, Turku (V)
Petrus Kurppa, Turun Ursa

Thursday is full of hope, and you could enjoy the sunshine according to the long formula. All sorts of nice little things at the hydrogen alpha wavelength, and one really spectacular burst!

Moon

13.8.2022 at 22.37 - 23.32 - Uusikaupunki (IV)
Sakari Ekko, Turun Ursa

For once, I happened to be in the right place at the right time, and the weather also favored shooting the moonrise.

Starlink-satelliitteja

14.8.2022 at 02.06 - 02.06 - Paimio (I)
Mika Aarnio, Turun Ursa

The Starlink satellite array photographed by Ursan Kevola's allsky camera in Turku.

Rocket-related clouds

13.8.2022 at 01.53 - 02.00 - Paimio (V)
Mika Aarnio, Turun Ursa

ROCKET LAUNCH from south to north almost through the zenith, VERY SPECTACULAR. The expansion of the final phase was no longer visible on the allsky camera, from our high tower I could clearly observe how the rocket gave birth to an expanding ring. #raketti: Falcon 9

M27

9.8.2022 at 23.30 - 00.40 - Turku (V)
Jani Oravisjärvi, Turun Ursa

The planetary nebula M27 was chosen as the first target of the shooting season, which is sufficiently bright and very spectacular even with a short shooting time. In the beginning, there were some technical problems due to software updates and own error solutions. Even though there is only 1 hour of light in the picture, one working day's worth of work has been done for it, if you include all the work from setting up the tripod to image processing. The intention is to collect more light later.

Quiet aurora band

8.8.2022 at 01.10 - 01.27 - Hyvinkää (II)
Senni Rytkönen, Turun Ursa

The air smelled of the possibility of rest. It may sound like superstitious nonsense, but for twenty years now, whenever the evenings get dark, the internal aurora radar starts to tune its frequencies into action, and on clear nights, sometimes I can't go to bed early when I want to see the start of the season (and August nights are the best anyway). This is exactly what happened last night. As the evening got dark, the northern lights app also alerted that something might be available later in the evening. The rain of the day had brightened the atmosphere like a diamond and I could see th...

Sun

7.8.2022 at 12.00 - Nummenmäki, Turku (III)
Petrus Kurppa, Turun Ursa

The sun of the day in three different lights. Calcium II K in the near-ultraviolet region, visible light (Baader Continuum) and hydrogen alpha light. In the close-up, the same sunspot in comparison. Seeing and the selected shooting configuration did not allow very good detail. Gambling with the clouds, but I was able to grab the screen if only the second one. Ca II K: TS Optics 80ED f/14.2 with aperture mask, Lunt Ca II K 12mm, Player One Apollo-M Mini. Close-up Televue Powermate 2.5x barlow. Visible light: TS Optics 80ED f/7, Lunt 1.25" solar prism, Player One Apollo-M Mini. Close-up Televue ...

Kari Nilsson, Turun Ursa

Kesäprojektin (DIY seurantalaite) testailua: 10x50s Denebin ympäristössä. Taivas oli vielä aika kirkas ja linssi meni huuruun, mutta jotain sentään tuli läpi.

Petrus Kurppa, Turun Ursa

A few words about the sun from last week's Tuesday. These were about to be buried in the table drawer when the weather was so bad, downright terrible. Seeing the daytime sky can often be bad simply because of local seeing, if the sun-baked roof of a neighbor's house is pointing in the direction of the sun, or the neighbor's grill is rattling in that direction. The exultant eruption on Thursday was already ready to show on Tuesday. Here are a few pictures in negative and positive. My attention was drawn to a small but peppery eruption that flickered on the other edge, from which the...

6.8.2022 at 13.06 - Turku, Nummenmäki (V)
Petrus Kurppa, Turun Ursa

Today, I was able to take pictures, when the sun was shining from an almost clear sky. A brisk wind finally made us move indoors with favor, when the clouds were crossing again. After a short break, more than hydrogen alpha, which is the sun imager's "candy". Sunspots can now be seen in abundance and are moderately large in size, so even in the image of the entire disk a penumbra around the spot can be seen beautifully. During shooting sessions, keep a cool head to assess whether to go into details with a barlow or continue to the next wavelengths. I ended up with the latter. As a pair of ...

Moon

4.8.2022 at 22.45 - Paimio
Eeva-Kaisa Ahlamo, Turun Ursa

August. It has become a tradition for me to start a new observation season with a feel-good session in Kevola. The forecast promises partly cloudy skies, but that doesn't really matter when the purpose is mainly to renew your acquaintance with the sky. I arrive in Kevola and open the Kepsi (Celestron GPS 11") roof. The Kepsi has been behaving badly, but Mika has gone to let it run, and now the pipe obeys without any problems. The background sky is still so light that I mainly study the bright stars and Kepsi's direction. The moon emerges from behind the clouds on the horizon. Eh, I did...

Petrus Kurppa, Turun Ursa

I was just about to bite into a pumpernickel over a cup of coffee, when a Turku-based sun photographer gave me a tip about a good view in the sun. Thanks only to Jan Laasanen, it was indeed a memorable sight on the surface of our nearby star! At first, the filming session seemed to dwindle as the clouds marched in, but in the end they just came to tease. Such large and spectacular eruptions can now be seen quite often when the maximum is approaching. Despite that, each time feels unique, as if you've never seen others before. Multi-image mosaic. DayStar Quark Chromosphere. TS Optics 80ED f...
