Half-sky auroras

14.4.2022 at 23.11 - 02.00 - Mustasaari (III)
Tommi Järvilehto, Vaasan Andromeda

A stunning northern lights eruption. It was visible to the naked eye all over the sky, even though the bright night and moon were almost full moon. The show is still in progress as of this writing .... Timelapse from 23:10 to 0:13. 5s exposures. Shooting direction west. Moonlight taken directly south.

Quiet aurora band

Tommi Järvilehto, Vaasan Andromeda

By nine o'clock it was still cloudy and the moon clear. In the north, however, there was a gap in the clouds and the northern lights intensified quite bright despite the moon. Red was visible at the bottom. I put the camera to shoot a series of pictures. n. 22.40 - 23.35. The northern lights were fading. I cut off the quiet part of the beginning. This time I made a vertical video. 10s exposures. The period was hit by another smaller period of activity. Even after a couple of hours, there seems to have been an even stronger episode, according to the Finnish Meteorological Institute. It was ...

Reposhäly. The moon is really bright, but the pictures show almost half the sky green. EDIT: It came later from the clouds. I added another little timelapse from 25min. 228x5sec

Half-sky auroras

5.3.2022 at 22.30 - 23.59 - Mustasaari (IV)
Tommi Järvilehto, Vaasan Andromeda

The bright northern lights came as a surprise. The prediction did not promise so great. The northern lights were over the zenith. The rays extended from the interval to the zenith when seen with the naked eye. The redness of the lower parts was also visible. In the final stages, spots that appeared and disappeared very quickly appeared. About 1,800 exposures in the timelaps video 2s. From 22:30 to 25:59. 24 fps

Aurora rays

Tommi Järvilehto, Vaasan Andromeda

The northern lights began to appear as early as six o'clock in the dark. The sky was green all night and night. Sometimes there were more active moments. The rays stood out well with the naked eye. Taken to Timelaps, a couple of shots from more active times. n.18.05 - 19.30 n.22.16 - 23.02

Aurora rays

5.11.2021 at 20.55 - 23.55 - Mustasaari (III)
Tommi Järvilehto, Vaasan Andromeda

Surprisingly, the northern skyline was bright neon green. The rays were visible to the naked eye in motion and even red stood out. Relatively impressive oh. The rays reached quite high. One star plane also appeared. For some reason, did not grip the camera cell. Timelapse compiled from two series of images. After the clouds came, I took another set. The second set would be longer, but the lens was fogged. The second series of pictures, I think, shows flaming northern lights. Big waves are advancing towards the zenith. 20.55 - 21.46 22.38 - 23.35

Quiet aurora arc

2.9.2021 at 00.15 - 02.50 - Mustasaari (II)
Tommi Järvilehto, Vaasan Andromeda

A G1 or G2 class northern lights storm was predicted for the night. The northern lights were pretty low but bright visually. It was relatively small, but it was just fine visually. I left the camera to shoot. The battery was exhausted prematurely. About a 20min break to the video. I guess to get flaming northern lights recorded in my place for the first time? In the middle stages of the video, rapidly expanding green rings of different sizes emerge from above the purple part of the arc of northern lights. Video reduced to 640p to fit in Sky Watch. part 1: 00:15 - 01:35 part 2: 00:55 - 02:50 15...

Aurigidit

1.9.2021 at 00.03 - 00.59 - Vaasa (IV)
Tommi Järvilehto, Vaasan Andromeda

I put the camera on the balcony to capture a series of city wasting light even if some Alpha-Aurigs grabbed the cell. Three remained for about 50 minutes during the shooting period. The clouds partially covered the sky from time to time. The first one at 12:44 seems to be the same as the others here in the Star of Heaven. It would be interesting to get a more detailed analysis of this now that there are several pictures from different directions in Finland. Picture 1 at 00:44 Fig.2 at 00:04 Fig.3 at 00:34

Diffuse glow

29.8.2021 at 00.20 - 00.35 - Mustasaari (I)
Tommi Järvilehto, Vaasan Andromeda

There were high expectations for the sequel to the great northern lights show of the previous evening. The closing season of the villa season was celebrated in fine late summer weather. I had to spend a lot of time outside admiring the sky. No northern lights were visible to the naked eye. I put a gopro to shoot jpegs from the sky at sunset until the morning. A few test shots were taken shakily at night. There was nothing in Järkkär's pictures, so I didn't put a series of pictures with it. When making the video, the faint reef lights stood out from the night images. The color editing a...

Active aurora band

27.8.2021 at 23.30 - 01.00 - Mustasaari (III)
Tommi Järvilehto, Mari Nordlund, Vaasan Andromeda

The bright moon diluted the visibility of the northern lights. The northern lights reached as far as the zenith. A strong eruption was in the sun. It was already thought there was a STEVE arc. The jet, clearly visible to the naked eye, baffled us. The camera image then later revealed the truth. More could be known tomorrow night.

At least 10 lightning strikes seen

15.8.2021 at 00.30 - 02.18 - Korsholm (IV)
Tommi Järvilehto, Vaasan Andromeda

On Sat-Sun night south / southwest Vaasa was approached by a night thunderstorm. No rumble was heard, perhaps at the end something very weak rumble. That is, these shots are actually from the Kalevant fire and lightning bolts. Distance from the shooting area approx. 60km alossa. At the end, the cell arriving from the south fused in its typical way before Vaasa. approx. 25km from the shooting location. At the end, the echo of the brightening horizon illuminates the highest clouds. There is no astronomical darkness at these heights at this time. FullHD version of timelapse: https://youtu.be/aJAd...

Clearly visible night shining clouds

13.8.2021 at 01.40 - 02.00 - Mustasaari (III)
Tommi Järvilehto, Vaasan Andromeda

The maximum night in Perseidite was cloudy from the beginning. I noticed at 1:00 that the clouds had receded There were also illuminating night clouds as a surprise. Were somehow look though a small area and down the northern horizon. Perhaps the contrast was greater when they were just visible at the time of maximum darkness. In addition, there were a few bright vertical lines. The clouds watched after about two o'clock. The first image is cropped from the latter original.

Tommi Järvilehto, Vaasan Andromeda

It was cloudy all evening. Finally, at about 1:00 a.m., I noticed that the clouds were about to give way. Out to detect and camera to take pictures. About 5 were visible during the 45min observation. One in the camera's license field. There was still a pretty light sky. However, it was great to be able to see in the end.

Half-sky auroras

17.4.2021 at 02.21 - 02.32 - Vaasa (IV)
Tommi Järvilehto, Vaasan Andromeda

At night there was quite a storm of northern lights. They were not very bright, but extended to the zenith, and spots could be seen with the naked eye, which disappeared fairly quickly and reappeared again. Were these pulsating northern lights? The video shows. I only took 1.6s of exposures. Timelapse from 02:21 to 02:32 352 x 1.6s exposures at ISO 6400 f / 2

A fireball at night, brigter than the venus

11.4.2021 at 02.47 - Mustasaari (III)
Tommi Järvilehto, Vaasan Andromeda

I left the camera for the night to photograph the northern lights. A pretty bright fireball must have been at dawn. 2 15s exposures. The stunned ball hit just between the two exposures. Frost on the lens. The third image is a combination of the two. Vana looks broken. Information missed between two exposures.

Quiet aurora arc

11.4.2021 at 00.42 - 03.33 - Korsholm (II)
Tommi Järvilehto, Vaasan Andromeda

Perhaps the last dark nights of the season describe repos. Contrary to forecasts, the weather was calm. It was great to watch the starry sky on the last full dark nights of spring. Geese that moved from the south kept the sound in the bay. A few starbursts and several bright satellites were visible. I left the camera to shoot in the morning. Frost had accumulated on the lens. At about 2:47 a.m. there had been a pretty bright fireball. I made this a separate canola. An orange flash appears in the timelapse video at 19s.

Mars ja Plejadit

2.3.2021 at 23.40 - Vaasa (III)
Tommi Järvilehto, Vaasan Andromeda

This encounter between Mars and the Pleiades had to be filmed. Next time in 17 years. Photographed on the shore of the center of Vaasa. It wasn't quite a clear sky, but enough. Even the northern lights green in the northern sky when seen with the naked eye. Rays formed by a nearby street lamp on the right side of the star landscape image.

Quiet aurora arc

7.11.2020 at 22.33 - 00.03 - Korsholm (II)
Tommi Järvilehto, Vaasan Andromeda

After the moon rose, a northern lights arc was relatively bright compared to the conditions. There was also a slight movement and the dim ray was visible to the naked eye. Although the moon was already quite up. The video shows a flash at about 15s. There was a fireball in the opposite direction of the camera at about 23:24: 40-48
