All-sky aurora

23.3.2023 at 22.20 - 01.55 - Ulvila (IV)
Vesa Puistovaara, Porin Karhunvartijat

Courtesy of bear cameras from the northern lights of the night between Thursday and Friday. First video compilation from 22:20-23:30. In those few individual pictures, the area covered by red is quite clearly visible, especially around 22:55(?) Especially in this second video summary (approx. 00:40-01:50) what caught my attention, or why I started to make observations about these in the first place, is the fact that the northern lights seem to be in a real "hurry" towards the east. According to earth.nullschool.net, the wind speed in the upper atmosphere (approx. 50 km altitude) seemed to be 5...

A fireball at night, brighter than the venus

Video recording of this fireball as well. As far as I can see, pretty straight down from below Arcturus the Guardian Bear in an easterly direction...

A fireball at night, as bright as a crescent moon

The fireball recorded by the bear camera (Karhu6/southwest) to support the visual observation made earlier.

Half-sky auroras

Vesa Puistovaara, Porin Karhunvartijat

An experiment to get a corona discharge on video recording with the south-west camera of Karhukamera (Karhu VI). The camera could not be turned closer to the zenith, but at least something was captured from this. --- EDIT: addition to observation (March 17, 2023): The Northern Camera recording before and after the rapid appearance of the corona eruption (around 01:00) is worth watching via YouTube. Too big a video to share here, but the video shows a lot of these repos as well! Especially the pulsation of the northern lights is better visible, because the individual images have a very short ex...

A fireball at night, brighter than the venus

There are a few visual observations about this fireball as well. Let's add an image with a time stamp.

Based on Tornio's observation, I looked through the recordings. It looked so modest in the wider pictures, so I tried zooming in on the pictures. It looks pretty messy, but you don't need to spray so much. Horisont's light cluster is the lights of the TuuliWati wind turbines in Peittoo recycling park.

Here is a visual observation made in Tampere. From the west coast there is also probably a recording of this fast fireball. (in the lower right corner of the picture)

I drove towards Lausti and while driving along the coast I paid attention to the area where it was raining heavily in places. At that time, there were reasonably high cloud tops visible in the west and northwest direction, but the drive plus getting to the destination and setting up the camera and tripod took a while for the cloud tops to be farther out at sea. I had promised to photograph the neighbor's excavator and a landscape constellation, well that came true but something else was also visible. Namely, the tiny ribbon-like rain area on the coast then took and flashed with great care....

A fireball at night, brighter than the venus

Vesa Puistovaara, Porin Karhunvartijat

From about 19:46:44 a ball of fire was visible in the northern sky.

EDIT: change to my original "fireball observation" Two fast-moving, darker nuggets caught my attention as they caused a brighter flash in the northern sky (video later). At the beginning of the video, they appear from the southwest sky, crossing Venus and Jupiter. The direction shifts to the northwest camera image, which clearly shows 2 separate 'fatiguing' lumps. In the image of the northern camera, the traces suddenly disappear, and after a while they return like flames. So it's birds (swans?) that fly past the star tower..and mistakenly resemble a ball of fire in their final fli...

Moon

26.2.2023 at 18.30 - 19.15 - Ulvila (III)
Vesa Puistovaara, Porin Karhunvartijat

26.2. the early evening provided moderate conditions for observing the Moon on the west coast. At last 2x with barlow noticed that now it doesn't look good. However, it was the best at that moment, so you just have to live with it. The purpose was to get some kind of mosaic put together again, and try to get a few details better recorded after that. Posidonius in the 2nd picture is ~100km in diameter, one of the finest craters in my opinion. The 3rd picture shows (at the top) Theophilus, to whose side Cyrillus and Catharina from the three largest are 'glued'. In the 4th picture, Pr...

Active aurora band

23.2.2023 at 23.20 - 23.42 - Ulvila (III)
Vesa Puistovaara, Porin Karhunvartijat

Bear camera footage of the aurora borealis activated about half an hour before midnight. The fog hindered observation from the ground, but fortunately the fog and cloud curtains did not hinder the observation on the roof of the observatory, let alone in the sky.

A fireball at night, brighter than the venus

Vesa Puistovaara, Porin Karhunvartijat

At about the same time (18:49:11), after one fireball observed from several locations, another one was also visible - admittedly not as long-lasting, but still a decent incident. Camera facing northeast, east right - Otava just visible. There was already another (and more spectacular ) recording of this here.

I saw this "live" myself, but now we will also add a video. Recording from the southeast camera, and the ball can be seen in the lower left corner of the picture.

Moon

1.2.2023 at 19.23 - 19.55 - Ulvila (V)
Vesa Puistovaara, Porin Karhunvartijat

The surprisingly cloudless early evening inspired me to photograph the Moon. I tried to get a few individual targets with 2x barlow (->5600mm focal length) better described, but the seeing was rather weak. For now, the image can also be viewed in full size (19mb) via the link: https://karhunvartijat.fi/kuu-1-2-2023/

I had time to photograph the northern half of the moon at the Ulvila observatory for a short time through quite a cloud cover. Mare Imbrium (Sea of Rains) is fairly visible surrounded by mountains.

Pearl clouds

Vesa Puistovaara, Porin Karhunvartijat

My first picture of pearly clouds. The active team of the bear watchers 'awakened' the visibility of this phenomenon, so I thought I'd try to photograph these colorful clouds myself.
