Ursidit

Markku Lintinen, Tampereen Ursa

Meteor from a video recording near the Vega star. Based on the direction of travel, it could be Ursidi.

Transit of venus

Markku Lintinen

At 5:30 a.m., the sun was variable through the clouds. Shooting equipment: Canon 20D, Sigma 28-300mm 1 / 250s, f / 10 ISO 400. Photographed through a Solar Skreen film borrowed from binoculars. Great opportunity to see the passage from the backyard! Last touch detected at 07:53:10 ... 07:53:15

Total lunar eclipse

Markku Lintinen, Tampereen Ursa

The upper level of the Kirkkoharju tower in Kangasala already had quite a lot of spectators and two cameras on tripods at the rise of the moon. However, the subject remained invisible in the thick air of a tropical warm night. As we left, we looked and binoculars for another moment in the corner of the school. At the very last moment, Mars succeeded and Mars also came into the picture.

Sun

Today, the morning of the summer solstice, was the milestone of a three-month solar photography project. Every week, I pick up one picture from the pictures of the east camera at the time of the sunrise. The moments of ascension described were not exactly scientifically accurate, but I could wait a moment if there was a narrow cloud belt on the horizon. I used imagemagick and ffmpeg for image processing. Between the still images, I counted the 50-frame transitions, and this morning’s sunrise, unlike the others, appears as a 45-minute time child summary. From the series of images, you can see t...

Sumusäteitä

10.1.2020 at 16.29 - Tampere (III)
Markku Lintinen, Tampereen Ursa

The western fireball camera of the Ursan Kauppi tower in Tampere showed a strange-looking shadow in the sky. Already 5 degrees behind the horizon, the sunlight cast a shadow from the steam cloud of the beach tunnel ventilation pipe into the sky. The camera that described the phenomenon shows a near-IR band - the visible light is cut off by a filter mounted in front of the cell. The direction of the sun is slightly to the left of the link mast. The phenomenon was visible for a few minutes.

Starry sky and bright summer night in the same picture. Lake Näsijärvi, which is partially freed from ice, reflects the light of the northern sky.

Markku Lintinen, Tampereen Ursa

Signs of autumn visible - Ursa Major arrives on stage. The moon also flashes on the right side as well as several satellites. The arc and rays of the northern lights that appeared at 02 o'clock raised only a hint of reddish reflection at this observation site. The camera is a new northern camera coming to the Kauppi tower in a test drive. From the still bright nights so far, it would seem to be quite suitable for northern lights and fireball photography. The sensitivity is in specs 0.0005 Lux and the resolution is 3840 x 2160. Time-lapse video is calculated from the recording with ffmpeg a...

Starry sky image

19.3.2020 at 21.38 - Tampere (III)
Markku Lintinen, Tampereen Ursa

The recently dimmed Betelgeuse shines brightly in the infrared image. The starry sky seen by the fireball camera is not quite familiar. Orion is dimly visible, as is Rigel. The brightest on the right is Venus.

Starlink

30.3.2020 at 22.01 - Kangasala (I)
Markku Lintinen, Tampereen Ursa

I was prepared to look for the ISS in the video, which is dimly visible above the clock. The surprise was the row of consecutive moving points above the ISS. They are likely to be Starlink satellites, even though, according to Sky Safari 6, they were not in sight at the time. Afterwards, I found that the entire satellite line was bypassed at 9:47 pm ... 10:05 pm. What a long chain of satellites!

Several bright halo forms

3.5.2021 at 10.30 - Lempäälä (III)
Markku Lintinen, Tampereen Ursa

On the way to the Lempäälä road, it was not difficult to notice the quite bright lower sun, from which I hurriedly took this picture. I would ask for help in identifying other halos. The east camera of the Tampere tower has a rather interesting video recording that is currently being downloaded. Too bad when the timelapse editor is waiting for a new linux installation, so no summary can be obtained for this trouble. I will make some points about it.

Rocket-related clouds

6.4.2019 at 01.21 - 01.24 - Tampere (IV)
Markku Lintinen, Tampereen Ursa

Based on observation 82249 from the table, two traces of Andøya's rocket launch were found in the recording of Kauppi's fireball camera. #raketti: Nasa AZURE 1 & 2 / Black Brant XI-A (rocket test)

Rocket-related clouds

27.9.2021 at 22.38 - 22.41 - Tampere (IV)
Markku Lintinen, Tampereen Ursa

With the help of other observations, this trace of the rocket's flight was also found in the recording of Tampere's northern camera.

Rocket-related clouds

28.9.2021 at 00.12 - 00.17 - Tampere (IV)
Markku Lintinen, Tampereen Ursa

Here's Rocket Night! According to the Sky Guard news, this would be an Atlas rocket seen an hour and a half earlier in the second round.

Rocket-related clouds

28.9.2021 at 00.11 - Tampere (III)
Markku Lintinen, Tampereen Ursa

The beginning of the visible part of the second round of the rocket in the western camera of Tampere. The sequel is better visible in the photo of the northern camera: https://www.taivaanvahti.fi/observations/show/101543

Rocket-related clouds

29.4.2022 at 23.00 - 23.03 - Tampere (II)
Markku Lintinen, Tampereen Ursa

Here is a continuation of the observation report of the eastern camera https://www.taivaanvahti.fi/observations/show/106515 as seen by the northern camera. The rocket launch cloud was very faintly visible in the bright northern sky. The maximum stack seemed to be the best way to make it visible. Thinned images also show two satellites in dotted rows.

Rare halos

2.2.2021 at 10.20 - 13.20 - Tampere (IV)
Markku Lintinen, Tampereen Ursa

Tampere showed bright side suns and a 22-degree tire. Edit: Tero, thanks a lot for the review! The cut you mentioned was a work accident after the hard drive of the recording machine filled up in the middle of 25GB of storage. I fixed the missing snippet. In addition, on the opposite side, the image of the northern camera showed weak signs of the counter-sun. As a directional aid in the second video, there is a shadow of the mast of the tower slightly to the left of the camera.

Quiet aurora band

6.5.2018 at 00.20 - 02.30 - Tampere (II)
Kari A. Kuure, Markku Lintinen, Tampereen Ursa

Probably the last northern lights of spring. The Night Eye Camera at the Ursa Observatory in Tampere recorded the northern lights dimly visible from the clear night sky during the darkest moments of the night. Here are a few screenshots of the brightest moments of repos. The Kp index rose to 6 during the night, so a G2-class magnetic storm caused these fires.

Quiet aurora arc

17.8.2018 at 02.38 - 02.42 - Tampere (II)
Markku Lintinen, Tampereen Ursa

As such, unnoticed northern lights, but I think it was unusual to have them and the illuminating night clouds in the same picture. The beginnings of the northern appendages also moved somewhat.

Perseids

5.8.2022 at 00.46 - 01.49 - Tampere (III)
Markku Lintinen, Tampereen Ursa

In the night of events in Tampere, in addition to illuminating night clouds and planets, there were also opportunities to see the early Perseids. I collected 19,000 pictures in a stack in an hour. Four possible Perseids and a few sporadic ones came into the picture. Individual dots may be traces of cosmic rays on the camera sensor. Additional pictures show the initial and final situation.
