Active aurora band

8.8.2022 at 00.00 - 03.00 - Tampere (III)
Kari A. Kuure, Tampereen Ursa

The first northern lights of the upcoming autumn season. The first rays of the aurora borealis were visible in the pale night sky a little before midnight, but the brightest repos were visible between 1 and 2 o'clock. At the same time, night clouds were visible in the sky, which were also bright, although very small. Here are some pictures of the two cameras.

Clearly visible night shining clouds

5.8.2022 at 00.00 - 02.10 - Tampere (III)
Kari A. Kuure, Tampereen Ursa

The night clouds were visible well, only to some extent Cloudiness hindered visibility from the previous evening. However, the clouds were not uniform and so the clouds were relatively well visible. In particular, the clouds were recorded clearly in Tampere's Ursa east camera.

Corona mass discharge. This morning, a coronal mass ejection will occur in the Sun, which was unusually bright when it separated from the Sun. By chance, I was filming when the weather was favorable and the CME was also recorded on my camera. Here are three different exposures and, in addition to them, a picture taken by SDO just a few minutes earlier for comparison. From the SDO image, I calculated the height of the visible CME cloud and ended up reading 188,500 km from the surface of the Sun. On September 1, 2022, I added one more picture to the end of the picture series.

Clearly visible night shining clouds

Kari A. Kuure, Tampereen Ursa

At night it cleared up for a few hours and that made it possible to see night clouds. Here again are the night clouds captured by a couple of cameras from the starry sky of Ursa in Tampere. This time there was not much to see, but it was quite decent. The first pictures are from the north camera and the last couple from the east camera. The time stamp in the images is UTC time again.

Clearly visible night shining clouds

19.7.2022 at 00.00 - 03.10 - Tampere (III)
Kari A. Kuure, Tampereen Ursa

Again, the cloudiness of the night made it possible to observe night clouds. The clouds partially retreated at the end of the day, but a little later they blocked visibility to the north. But fortunately not for very long and the clear area expanded enough that the night clouds were visible until 3:10 a.m. The distance of the sun from the horizon was then about -4.5 degrees ( see the discussion of my previous observation! ). Most of the pictures are from the north camera, but the last couple are from the east camera. You may not be able to see the westward movement of the night clouds in these...

Bright night shining clouds

15.7.2022 at 00.45 - 03.20 - Tampere (IV)
Kari A. Kuure, Tampereen Ursa

The first decent night clouds for this year. Some indications of the starting season have been seen in the camera recordings about a week ago, but since then Cloudiness has blocked the view of the sky. The pictures are from two cameras: the first four from the north and the last four from the east. In Tampere, the night cloud season starts in mid-July and lasts until mid-August at most.

Rocket-related clouds

29.4.2022 at 22.59 - 23.01 - Tampere
Kari A. Kuure, Tampereen Ursa

Rocket launch. The rocket launch, which was widely seen, was also recorded in the eastern weather camera of Ursa in Tampere. Selected images from the recording here. The last couple of dry ones have been croped and I also added a timestamp to them. The video can be found on YouTube at https://www.youtube.com/watch?v=y6PCnT7c1G8&ab_channel=TampereenUrsa

Active aurora band

14.4.2022 at 23.33 - 04.17 - Tampere (III)
Kari A. Kuure, Tampereen Ursa

Northern lights that lasted all night appeared in the sky as the evening darkened into night. The night sky is no longer completely dark at this time of year, so the contrast between the repos and the background sky wasn’t quite what one might have expected: the northern lights looked a little modest. The northern lights activity was visible until dusk and probably continued until the early hours of the morning. Here are a few pictures of the best moments, the last couple of pictures are already at dusk.

Quiet aurora arc

13.4.2022 at 00.55 - 04.13 - Tampere (II)
Kari A. Kuure, Tampereen Ursa

Very dim and calm northern lights at night in Tampere. The brightest moments took place between 1 and 2 p.m., for about 45 minutes. In those moments, the northern lights were so bright that they could be separated from the sky with the naked eye. The camera recorded the repos from 1 o'clock until dawn, ie until about 4.15 am. Here are a few pictures of the brightest moments. The last image is from the dim phase of the northern lights, when only the camera could detect them.

Half-sky auroras

13.3.2022 at 19.00 - 05.00 - Tampere (IV)
Kari A. Kuure, Tampereen Ursa

Northern lights were noticeable almost all night. In the morning night they dimmed and in the evening there were long breaks, when only a dim northern lights were visible in the sky. But the repos at times were bright and fast-moving. Here are a few pictures in random order.

Half-sky auroras

10.2.2022 at 18.50 - 06.00 - Tampere (IV)
Kari A. Kuure, Tampereen Ursa

The northern lights blazed all night, although the brightest moments were experienced and seen in the evening and evening. Here is a picture from the video camera of the Ursa Observatory in Tampere. In the brightest moments of the evening, the northern lights extended from east to west and probably Korona was also visible. Our Allsky camera is out of the game, so it’s certainly not possible to argue that the corona is visible. In the morning and at night, an arc of northern lights of varying brightness was seen. It only disappeared from view at dusk.

Quiet aurora band

24.1.2022 at 23.00 - 02.30 - Tampere (II)
Kari A. Kuure, Tampereen Ursa

A calm northern lights belt and some rays were recorded in the northern camera of Tampere's Ursa. I was expecting a little brighter fire but for some reason the magnetic restlessness did not develop to the degree of a storm.

Active aurora band

15.1.2022 at 01.45 - 05.10 - Tampere (III)
Kari A. Kuure, Tampereen Ursa

The northern lights of the morning began as a calm arc but very quickly turned into an active belt with rays. The fast-moving fires were that in some images they appear more or less diffuse.

A fireball at night, brigter than the venus

21.11.2021 at 00.13 - Tampere (III)
Kari A. Kuure, Markku Lintinen, Tampereen Ursa

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.

Active aurora band

20.11.2021 at 22.45 - 01.30 - Tampere (III)
Kari A. Kuure, Tampereen Ursa

The clear evening made it possible to record the dim northern lights in a video camera located at the Ursa observatory in Tampere. The northern lights had several different shapes from the gauze to the active belt. As a small specialty, the lower edge of the arc of northern lights was also unusually bright and wide for a while. The brightest stages took place around 11 p.m. and midnight. Eventually, the clouds increased, obscuring the view of the sky.

A fireball at night, brighter than a full moon

11.11.2021 at 04.52 - Tampere (III)
Kari A. Kuure, Tampereen Ursa

A bright car with a duration of about 5 seconds was stored in the northern camera of Ursa in Tampere. I summed up the video from the individual images and made an edited video that can be found at this link (YouTube).

Quiet aurora band

8.11.2021 at 23.25 - 00.30 - Tampere (II)
Kari A. Kuure, Tampereen Ursa

Clear weather allowed distant northern lights to appear. The dim northern lights began to appear on the north-facing video camera at about 11 p.m., but the northern lights actually brightened about half an hour later. The brightest moments were between about 23.40 and 23.45. Here are a few pictures and videos on Youtube at https://www.youtube.com/watch?v=rXcvM8SmGPk

Active aurora band

18.10.2021 at 21.00 - 07.00 - Tampere (III)
Kari A. Kuure, Tampereen Ursa

The northern lights of the night of 18/19.10.2021 were active and bright at the time of the strongest sub storm, which began at about 00.50 and lasted for about half an hour. Before that, when the evening was dark enough (about 9.45 pm), a dim and calm belt of northern lights appeared in the sky, where dim rays occasionally appeared. Going towards midnight, the activity increased, the belt turned into an arc of northern lights where randomly moving brightenings and the formation of rays were occasionally seen. Then, shortly before 1 o'clock (Finnish summer time), bright and very active nor...

Auroras seen through breaks in the clouds

12.10.2021 at 21.00 - 23.59 - Tampere (III)
Kari A. Kuure, Tampereen Ursa

Northern lights from cloud crevices and partly through clouds. The G1-class magnetic storm brought with it northern lights, which were also visible in Tampere. However, the cloud cover was relatively strong, so this time we only had to settle for repos visible through cracks and through the clouds. I also uploaded the video to YuoTube's Ursa channel in Tampere, the address is AB2021102
