Half-sky auroras

Markku Lintinen, Tampereen Ursa

The composite video of Tampere's northern camera is limited here to the brighter after part of the northern lights. The show started dimmer already at midnight.

A fireball at night, brighter than the venus

27.9.2022 at 20.22 - Helsinki (III)
Otto Vehviläinen, Ursa (Helsinki)

I was sitting on the balcony adjusting the telescope when a fireball appeared in the sky. From the vantage point, it appeared to drip almost straight down, flashing green around the yellow heart.

Active aurora band

22.9.2022 at 22.30 - 01.30 - Kittilä (III)
Satu Juvonen, Ursa (Itä-Suomi)

This is probably a basic set in Lapland. The great northern lights, whose brightness was accentuated when the Moon was hidden and there is no wasted light in the nearby countries. The fires stayed pretty low. On the shore of Pallasjärvi at the Punaisenhieka hut, there were several wonderers and the atmosphere was devout, the lake was calm, the silence and darkness almost perfect.

Half-sky auroras

27.9.2022 at 02.50 - 05.00 - Mäntyharju (III)
Jukka Kytömäki

A slow and slow start, but then started with high beams. Gradually over half the sky mixed movement, the coloring varied in variety. Pulsating spots and gentle corona alternately. A dense fog is present all the time, making the pictures blurry. Also a strange curly cloud high up. Fortunately, the repo colors were clearly visible, at least from the machine.

Several halo forms

Ismo Pyhtilä

I was in the birdwatching tower watching birds and looking straight up at the sky I caught a halo. At first it was dimly visible, after which the colors intensified and the halo became more clearly visible.

Quiet aurora arc

24.9.2022 at 21.30 - 23.50 - Nurmes (II)
Eero Karvinen

At first it looked good, Bz is diving into a long negative period and the speed of the solar wind is still high. However, all good things come to an end. a combination where Bt decreases from the value 6 to the value three and at the same time the field turns north (positive Bz value), then the coupling of the particles to the magnetic field created by the earth becomes more difficult and at the same time the pressure on the field decreases, so you know that. However, the peaceful oval with its dune mounds delighted the night sky. The substorm ignited even later when the plasma tail finally br...

The bridge over the sunspot. Area AR3105. I've seen these bridges before, but haven't managed to photograph them. I'm not sure if it counts as two commas or one, with a bridge going over it. Two large filaments also stand out in the picture. The overexposed spot above the colon is apparently a small blur. The color doesn't quite match the one seen in the eyepiece, it should be redder, but when edited this way, the bridge and the penumbra around the little one can be seen better. The first successful image with the new self-assembled tube: Lunt 80 standard + Skywatcher 150 refra...

One halo form

24.9.2022 at 19.10 - Vaasa, Meteoriihi (I)
Timo Alanko, Vaasan Andromeda

We spent an open-door evening at our Meteorii in Söderfjärden. Its aim this time is to crown the evening flight of approx. 9,000 people to the sea to spend the night. Fittingly, the direction was towards the sun pillar. More bird photos as a bonus.

A fireball at night, brighter than the venus

14.8.2022 at 23.44 - Ulvila (III)
Kalle Luotola, Porin Karhunvartijat

I tried to photograph the heart fog and the soul fog, and in that noise, this fireball, possibly the Perseid, was recorded on the camera. I didn't see this particular fireball, but an interesting looking one fading and brightening again. The fix: Probably a satellite or some other man-made space debris. I checked the clock on the camera and it advances for about 3 minutes. It would be interesting if that Viiru cause could survive.
