Light pillars

6.12.2021 at 22.31 - Tampere (II)
Markku Lintinen, Tampereen Ursa

In the evening of Independence Day, handsome artificial light pillars were visible in Tampere. To the east, a huge flux of light escaping from the central hospital area into the sky is an uncomfortable phenomenon that, after its recent increase, has already severely hampered observations.

A fireball at night, brigter than the venus

The long-seen car was recorded in the northern and eastern cameras of Tampere's Ursa. Here is a preliminary image from the video. Unfortunately, every second picture is missing due to technical issues. I will update the pictures as soon as I can build more of them. 22.11.2021 update. Here are a couple more photos that were manually excavated from the video containing the errors one frame at a time. Unfortunately, not everything was saved, but some were. The added images are from the north and east cameras.

Diffuse glow

4.11.2021 at 21.40 - 22.35 - Tampere (I)
Markku Lintinen, Tampereen Ursa

Here is a more negative northern lights observation and an observation of the possibility of seeing northern lights that appeared strong in the models a moment earlier. The video has a lot of flashes due to corrupt screens, which I didn’t bother to edit out of here, though. Better coincidences of cloud holes and celestial events are still expected.

Active aurora band

19.10.2021 at 00.55 - 01.00 - Tampere (III)
Markku Lintinen, Tampereen Ursa

Rarely do you see such bright northern lights in an east-facing 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

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.

ISS

26.9.2021 at 20.30 - 20.34 - Tampere (IV)
Markku Lintinen, Tampereen Ursa

Sky Safari alerted "ISS (Zarya) rising". Good when reminded. This was my best observation to date at these latitudes. The video is somewhat accelerated. The ISS disappears into the shadow of the earth shortly after passing Jupiter. Even on Monday night, this is worth a look. Still quite clear skies may appear in the south at about 19:45 and in the direction of Jupiter at 19:47:30. The next round rises from the southwest at 21:17 and disappears into the shade just before noon at 21:22.

Starscape image

30.8.2021 at 00.00 - 04.55 - Kangasala (IV)
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...

Perseidit

13.8.2021 at 00.55 - 01.20 - Tampere (III)
Markku Lintinen, Tampereen Ursa

Many times Persians have been viewed under the open sky and the storm has been welcomed. This time I was an armchair astronomer with a corrected celestial camera recorder allowing the observation window to be moved to dusk. Four Perseids appeared in this interval. I changed the timestamps a couple of days ago to UTC.

Bright night shining clouds

10.8.2021 at 23.00 - 04.30 - Tampere (IV)
Markku Lintinen, Tampereen Ursa

It was little that this observation had not been made either. The hard drive of the video recorder disappeared again after the morning configurations. In the afternoon I went to the tower to persuade the device and still thought I could get extra time. The night clouds did not rise very high this time, but they were beautiful as such. The hurried child made in a hurry had some extra left at each end.

Bright night shining clouds

3.8.2021 at 23.30 - 04.15 - Tampere (IV)
Markku Lintinen, Tampereen Ursa

In the wake of the fireball noise, while checking the cameras, I came across a play of colorful night clouds. The cloud pattern slowly expanded from northeast to far south. After all, a small glimpse was also found in the fireball seen by many. In the east, the moon advances racing with the clouds and in the saturated image disappears into its cloud mass. There is a brightness jump in the image of the eastern camera when the camera switches out of HDR mode at a timed time soon after the start and returns to it at 3:30, which also distinguishes the brightness ratio of the moon and clouds. The m...

Other storm phenomenon

31.7.2021 at 01.00 - 02.30 - Tampere
Markku Lintinen, Tampereen Ursa

After midnight, strange-looking cloud formations moved over Lake Näsijärvi. In appearance they resembled avalanche clouds, but the movement was more longitudinal and below the cloud there were no strong winds reaching to the surface of the earth. The closest equivalent would appear to be the morning Glory cloud.

Eye-catching night shining clouds

20.7.2021 at 23.45 - 03.45 - Kangasala (V)
Markku Lintinen, Tampereen Ursa

The super night clouds were in the sky when I happened to glance out. A breathtaking sight live - extended far to the south sky. The start was seen about an hour earlier in the camera recording. EDIT 1.8.2021 Yet I saw as a reminder today a compiled timelapse of night clouds of super night.

A fireball in a twilight sky

15.7.2021 at 01.20 - Tampere (IV)
Markku Lintinen, Tampereen Ursa

Summer is already starting to darken and more is starting to show than Sunsets and night clouds. The previous evening ball fired by many was not found in the pictures from Tampere's cameras, but the last one recorded an earthy-looking calm flight of just over 6 seconds. The direction of Saturn, which also came to be observed here for the first time this summer. A little later, Jupiter also became bright in the picture area. Pictures taken from the beginning, middle and end of the flight.

At least 5 lightning strikes seen

8.6.2021 at 00.00 - 00.30 - Tampere (III)
Markku Lintinen, Tampereen Ursa

A summer thunderstorm moved slowly to the southeast in the direction of Orivesi. The flicker was within reach of the eastern camera from midnight onwards for a couple of hours. Here are a few flash observations taken from the first half hour.

One halo form

1.6.2021 at 22.55 - 23.55 - Tampere (I)
Markku Lintinen, Tampereen Ursa

The sun pillar came into the corner of Tampere's northern camera ten minutes after sunset and was visible for an hour.

Lightning photo

17.5.2021 at 15.24 - Tampere (III)
Markku Lintinen, Tampereen Ursa

The photographer of the observation https://www.taivaanvahti.fi/observations/show/98408 has had the great fortune to get a picture of the lightning strike at Näsinneula! Based on the observation, I was looking for a fireball camera in the recording and at normal speed, it would have gone unnoticed without the timing of the second observation. At 20 fps, the flash appeared in only a few frames.

Moon

17.5.2021 at 01.30 - 03.30 - Tampere (IV)
Markku Lintinen, Tampereen Ursa

The fireball camera equipment in Tampere's Kauppi tower has a PTZ surveillance camera as a temporary northern camera. In terms of sensitivity, it corresponds to the previous Hikvision darkfighter camera, which broke down some time ago, but here the optics are clearly better. The 12x zoom and rotation capability are poison in fireball shooting, where the calibrated camera should stay in a pixel-precisely set direction, but for starry landscape photography, this is a nice fit. A lot of interesting details have already been found in the landscapes of Lake Näsijärvi and Tampere, which I will d...

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.
