Artificial light pillars were also captured in the northern lights timelapse shot by GoPro. The video is cropped from the original timelapse, picture 2 is uncropped but lightly processed. There are several settlements in the direction of the pillars: Juva 20 km, Joroinen 51 km and Varkaus 66 km.

The magnificent aurora borealis all over the sky started as soon as the sky got dark. For a long time, the green cloud covered almost the entire sky and most seemed to be happening directly overhead. Several cameras shot timelapse in different directions, there was also something to shoot in the south direction. Figure 1. "Aurora borealis bubble" facing south at 22:56-00:29. Figure 2. Full sky at 21:18-22:04. Figure 3. Eastern sky at 22:22-22:57. Figure 4. Eastern sky at 20:56. Figure 5. Western sky at 21:32. Figure 6. The whole sky at 21:55. Figure 7.

Riikonen communicated throughout the afternoon about the promising pyramid halos seen in Kontiolahti, but the sky here remained stubbornly overcast. The lower clouds did not disappear until around five o'clock, but the upper clouds that appeared behind them seemed very inhospitable. However, I took several hundred pictures just in case. Short pieces of 18° parhelia were found in a few stacks. That was it. Figure 1. Stack of hundred pictures at 17:14-17:42 (2xusm, bg). Figure 2. The previous one only in usmat. Figure 3. The first image of the stack without manipulations.

To the south of the aurora arc, the green spots that appeared on land at 10:10 p.m. strangely caused movement in the joints of the repos photographer. First I went to a suitable place to shoot a timelapse, then to get another camera for full-sky photos. Despite the small mess, something managed to be saved. In the pictures, next to the green arc/spots, a red arc also stands out a bit. The timelapse of the main picture was shot at 22:15-22:37. The video first shows the unprocessed images and then the same images with the knobs in the southeast. The pictures were 20 second exposures (15 seconds ...

Quite a September evening. Gentle southerly wind, still warm at midnight, 18 degrees, and the camera lenses were not caught in the fog at all. The sky also remained clear until midnight. And what auroras! With the naked eye, you could mostly only see the green streaks, but luckily the cameras record other colors as well. The time of observation is the period covered by the GoPro video (picture 7) from 20:50 to 00:33, the full-sky video was taken from 21:38 to 00:23. Pictures 1-6 taken between 21:33 and 22:40.

The warm southerly air flow continued, but there were hardly any halos visible in the upper clouds. In addition, low clouds hindered the observation of haloes almost all day. It was momentarily clearer at half past three and there seemed to be an extremely dim arc above the Sun. So put the pile on the fire in a hurry. I managed to get a few tens of pictures of a clear sky, until the lower clouds came to bother me again. The stack revealed a weak 23° upper parhelia and a patch of 18° parhelia (pictures 1-4), as is expected in warm air flow. The "9r" that stands out in the pictures is possibly a...

Riikonen was texting in the evening and suspected, based on the weather forecasts, that a pyre might be coming. Be that as it may, right in the morning a very weak diffuse ring around the Sun was visible to the naked eye. Stack on the fire and get the pyres! There may be more to come, so keep an eye out. EDIT: Added three consecutive stacks with more shapes. In the first one (picture 4), attention is drawn to the arc going from the right-hand sauri to the left in an upward angle, which may include a 24° ring, or something else. The middle stack (image 5) shows Parry and the last one (image 6) ...

A flash was found in the GoPro images that seemed to match the fireball that was observed in a few places at 11:44 PM (marked as the observation time) within 10 minutes. The flash hit two consecutive frames with exposure times of 10 seconds. I don't know the length of time between pictures. In the main picture, those pictures have been combined and cropped, pictures 2-3 are the original pictures. I will also include a flash recorded a little after midnight, which may be a fireball (picture 4). At least this time, it was quite difficult to find out the exact times from the GoPro timelapse. ...

The most active phase of last night's aurora borealis filmed by GoPro and lightly edited. The recording period of the video is marked as the time of observation, which is indicative. As the second image, one screenshot from the video.

In the picture taken by Tuula Summanen (picture 1) in the morning, a bit of dew arch was visible, so I headed there with the drone. The wind had picked up and the dew had dried, so I was satisfied with photographing the surface of the water from above. But you can't really see from those pictures what had caused that film.

A spectacular airglow from a few nights ago, or was it? There is already one aurora sighting from the same night on the lookout and pictures from different places on social media about this phenomenon. I photographed the Milky Way at night for fun (picture 1), when the conditions were excellent for once. As a bonus, green "air glow streaks" stuck to the pictures. However, I drew attention to the fact that earlier in the evening I had photographed very similar clouds from the same part of the sky, both in the stack and in the drone panoramas. Doubts arose and I pressed back to the field to phot...

Half-accidentally, a reasonably clear 22° upper side opening and a bit of basic roll caught the stack from between the rain clouds. No other halos were visible today. Figure 1. Stack of 50 images at 16:14-16:16 (2xusm, bg). Figure 2. The previous one only in usmat. Figure 3. The first image of the stack without manipulations.

In connection with the afternoon rainstorm, it became a suitable situation to try to photograph rainbows on the sunny side. I rushed with the camera to the corner of the house under the eaves and started the stack. I concentrated on protecting the lens from drops and didn't blink much at the sky. It was quite a surprise when I got a glimpse of the footage of the first stacked version. There seemed to be some strong horizontal lens flare on the sun when there was no mask in use. There has never been such a reflection before, what a wonder... for a moment... it was a halo! 22° upper side ope...

Hopes for a good pyramid halo day dwindled to the disturbance of the lower clouds. Somewhere in between, however, I recovered a small stack, from which I found several shapes after all (pictures 1-5). Illemma was a bit clearer, but only basic shapes remained (picture 6). Of the marked shapes, sauris and 22ys stood out better in other pictures. Figure 1. The first image of the stack without processing at 12:40 p.m. Figure 2. Stack of 37 images at 12:40-12:43 (2xusm). Figure 3. The bg version of the previous one. Figure 4. The same stack mirrored (3xusm). Figure 5. And bg processed. Figure 6. St...

Halos throughout the afternoon. First the basic roll, then more interesting shapes. Low clouds disturbed the observation quite effectively. Figure 1. Stack of one hundred pictures at 13:17-13:33 (2xusm, bg). Figure 2. The previous one only in usmat. Figure 3. The first image of the stack without manipulations. Figure 4. A stack of one hundred images at 14:53-15:09 (2xusm, bg). Figure 5. The previous one only in usmat. Figure 6. The first image of the stack as organic. Figure 7. Stack of 80 images at 17:34-17:47 (2xusm, bg). Figure 8. The previous one only in usmat.
