In connection with the aurora emergency, in the course of a couple of hours I saw a dozen distant flashes of lightning from behind the horizon. Like flashes of electric welding. Most of them from behind the western horizon. According to the radar, there was a weak thundercloud to the west of Päijänne, somewhere north of Hämeenlinna, approx. 150 km away. At the end of the day, a few flashes in the north, which according to the radar was a thundercloud in the direction of Viitasaari, about 200 km away. In the picture, the western horizon, behind which you could see the kaleidoscope. The weather ...

We watched almost non-stop lightning and flashes. At the same time, I let the camera sing ~1600 pictures. About 40 of which remained from the first slaughter. Sony A6000 as lenses, old film-era glasses. JcPenney 28mm F2.8 and Yasciha 50mm F1.7. Exposures 2.5-3.2s and the big value quite small.

While I was at work, I was cursing the radar images of the Finnish Meteorological Institute, wondering how I would miss all of it... Fortunately, I was able to leave a little earlier and on the way home the sky flashed quite spectacularly. After getting the car parked, I quickly got the shaker from inside and started recording the flashes of the flash. Unfortunately, the best glimpses were probably visible during the journey home, but someone who went into a mug grabbed the camera's camera. I managed to photograph for a good twenty minutes before the starting rain forced me to move the cam...

Again, frequent lightning was approaching towards the town and again the fatbike was in rapid use. To Vihiluoto, of course, that's where the leaky canopy keeps the most drops away from getting the photographer wet. We were there on time and had time to look for landscape perspectives and marvel at the sky, but a couple of curls in the clouds above attracted so much attention that we had to photograph them with an iPhone and there was no time to do anything else about them. They were already gone by the time I got to the store. In the end, the avalanche cloud started to stand out and the wi...

I don't remember such a great lightning day ever as it was today. After the afternoon thunder, the rumbling continued until the morning and beyond, but I had to go to bed. A few successful frames from a memorable day.

Timo Alanko, Vaasan Andromeda

It's thundering properly on the gusty side. Ground lightning is rare, but the rumbling is sometimes continuous. A storm cloud could be seen in the front of the front, but that brutally massive Kelvin-Helmholz just stole my attention. I wouldn't really call that undulation anything else. Maybe add your own observation later. Photo with Mavic Mini. Edit. Around the same time, with the same screams, the edge of the thunder front itself, i.e. I was following comfortably during the hour. Let's put a suggestion of a storm cloud as the second picture. Maybe not quite typical either.

Thunder rose from the sea. I followed the radar and estimated that a fairly good lump would rise somewhere between Lieto and Marttila. There then. Well, it did rise. But right in the area where I was standing, the front crashed. Good areas went by on both sides. I didn't dare go after them anymore, so I tried to save what could be saved. However, something was caught. And I got the flash with the still unthreshed grain field in the same picture. The air was really grinding.

Already earlier in the afternoon, a wider front passed from the observation point to the west. However, a few glimpses stood out despite the distance. Later, a smaller cell passed over, momentarily offering plenty of water and several flashes. I tried to video the latter case for a long time with the flash in mind. I recorded in slow motion at 240 fps. One eruption hit the image area, and then when watching it on the recording, several branches came off from it. In a live situation, that marking felt like a single flash with my own "sensors". Of course, the eyes were on the screen of the hands...

Today was the most thunderous day of the summer for me. I was at work, but we went by car over the fell to watch lightning. While driving home from work, Storm damage was visible along the 5th road at the Juuma fork and on Juumantie, where a huge amount of trees had fallen a moment earlier. The fire department cleared the roads. Many trees had fallen in the same direction. It must have been a strong rush that brought down the trees. A gust of wind had suddenly risen at the Juuma measurement point, but no felled trees were visible there, but the worse damage was approx. 10 km away. It also rain...

Around half past three, the first flash appeared in the western sky, I had already thought that the approaching thunder would be invisible again due to the rain. When the flashing started, it continued for more than two hours, although part of the sky remained behind the houses, more than 100 flashes of lightning or clouds illuminated by lightning were captured in pictures. that's how far it went. It would have looked pretty from Ruissalo's beach, but it wasn't time to go there at two in the morning. Maybe there's a chance for a nocturnal thunderstorm trip. The last lightning w...

The forecast predicted a night thunderstorm in the Turku region. I set the alarm to wake up at two and collapsed into the blankets. When the clock chimed, I got up and looked outside for a moment. Flash. The rain radar also revealed that a thunderstorm front was approaching. I estimated that it runs along the coast of Turku in the direction of Pori, so I decided to drive to the rock of Vanhalinna, from where I assumed the lightning could be seen comfortably. And yes, the lightning was nice to see. Very comfortably. The distance to the thunder was about 15-50 kilometers. The air was hazy with h...

After all, we got that "concentration" here too, because a little before one in the morning, a thunderstorm started approaching from the direction of Kauhajoki, which really was as if a battery of a thousand tubes had opened a drum fire. Nothing really came of sleeping, but the rain that preceded the thunder on the other hand made sure that you couldn't even shoot without the camera getting wet, and there are trees in front of the back terrace. Then I thought that I would wait for the thunder to pass by and go to the terrace in the front yard to film a proper light show, but the thunder di...

I started Chase from Pyhäranta, where the clouds prevented the recording of the thundercloud at sea. The radar revealed a small but heavy raining and lightning area coming from the south, which I was driving towards. The lightning was fierce and seven lightning bolts were currently striking at one time. The lightning area spread quickly after reaching the mainland. Edit. I added, for example, a picture of a lightning strike on a target.

Distant night thunder occurred around Pori on the night of 18/19/8/2022. During the night there was mainly a cloud fire, some live lightning was visible. Mainly the lightning struck inside the cloud and mostly the catches were flashes inside the cloud, but I was able to record two actual lightning strikes. The flicker was active during my observation, the flicker was visible in the sector extending from the west through the north to the east. It was difficult to photograph when it was flashing in every direction, and you didn't know which direction to photograph. There were some distant, m...

I had already packed my camera backpack so that I would try the opening of the northern lights season after 11 pm when I get off work. After the sun went down, a terrible flash began as the thunder rolled over the sea. After the end of working hours, the ankle is straight towards the observation point and the flash on the horizon was continuous. 10 kilometers before the destination, I thought I'd take a few pictures, because it started to look like the flash was fading. That's how it happened, the best parts were already gone, but I still got a few pictures. Unfortunately, there were t...

In the early evening, a thunderstorm front rising from the southwest reached Vöyri. I photographed it from the side from Vaasa until its rain area spread to wet our copter as well. I think there was a cumulus cloud at the edge of the cell. I also looked towards the sea from time to time for water statues. I don't know what those ribs on the right are... The swallows visited many times to marvel at Mavic :)

This thunder came as a surprise. Quickly gather the filming equipment and go a short distance from the house to the edge of the field to photograph and admire. It's fair to say that I was actively lightning, the bills got messed up after 25 songs. Also nice slow motion and what's best, the photographer stayed dry from the rain. The picture is taken from the video.

Yesterday I had to stop by the observation tower of Pirulanvuori to check how the thunderstorms in the direction of Tampere look from there. This time too, the reflex trigger didn't get any flash in the picture, even though there were plenty of them. It was great to watch as the thunder front swept past with a huge wall of rain.

The almost continuous rumbling and flashes lasted for a long time. I don't own a flash trigger, so I shot the flashes by video. From the still images captured from the video, I compiled this composite image of the flashes of lightning seen during about seven minutes around 7 p.m. It's a bit difficult to count the number of separate lightning strikes, but there are twenty flashes in this picture.

Surprisingly, a very lively cell hit Tampere when I was returning home from the movies. I had to be sheltered from the rain for quite a long time under Näsinstilto. It's a shame that the rolling shutter of the cell phone camera can't really capture lightning. I combined 2 consecutive frames of the LightningCamera application into the main image.

When Myter came to the village, it hurt and happened. It was a violent thunder. The lightning also lit a fire there before my eyes. Nothing but a call to the cage. I had to pass out because the fire gases from the burning building spread over the area. Quite an eventful trip.

" If I paint the shed now, I'm sure there will still be a set in there for the evening ", I said in the afternoon, in pain, the active-looking fierce wind passing by from the west. It was well beyond the bongar's range. So I put paint on the brush and got to work. This order clearly went to the right address. As the evening grew dark, a steady rumble approached from the south, and the approaching line across the water was like a well-shaped cumulus cloud. The lightning and heavy rains passed quickly and with force. I looked to the east with the camera, while Marko observed the continue...

For almost half an hour, I watched the gales, which told me that a thunderstorm was approaching from the south. Jylinä started to sound even closer. Then, from the light poles and maybe other metal pieces nearby, a nice chirping sound started to be heard. I thought it might be wiser to jump inside the car now. A good decision, because after about 10 seconds, the lightning struck nearby (main photo). How close? Based on the rumbling delay, I guessed that it was less than a kilometer away, but the positioning data showed a landfall about 4 km away. Lightning moved to the north side, and there wa...

Lightning was already approaching around Kalajoki and then it was fast to jump on the fatbike and with the favorable help of the downwind, the cycling to Vihiluoto went quite fast. The hamstrings seemed to be strong, but we got there. A handsome cloud front approached and the iPhone captured the first lightning photos from afar, but that cloud didn't fit in the picture area at all, but soon there were insects all over the clothes and in the camera and tripod and lens and glasses and what lies. Soon the storm was right on and then there was a rush to one of the roofs and water came with qui...

As the thunder front approached, I thought that the series of maximum stacks that worked for the Perseid photo might work for the lightning photo. I adjusted the north camera to a faster 20 fps for the duration of the shoot. There was still one finishing touch left to try for the next shooting: the gain of the sensitive sensor should have been adjusted to the minimum, so that the exposure time would have been even a little longer. Now, many flashes were probably not captured, even though the video turned out to be a total of more than 100,000 images to be stacked and these flashes to be picked...

Morning thunder raged in Laitila. It started on the western side of the sea at three in the morning. From there, the system progressed in such a way that when the thunder from the west finally moved to Pori, a terrible wave started to move from the south and at the same time lightning started to flash again, it was a really fast storm. The raining and thundering area was small in the morning, but very peppery and it actually flashed when it came to a break. I think I saw an anvil crawler, you see these less often. I dared to check it. I got quite close a couple of times and there are a couple ...

The last days of thunder. Lightning continued after dark in the evening in the direction of Maksamaa archipelago. I took the Mavic into the air one more time. On the first attempt, it drove itself into the wall again. I think I want to retire :). Another company agreed to work and videoed in the direction of the archipelago for a few minutes. I didn't see any lightning, but those three ground lightnings now.

Earthquakes still developed at the rear edge of the violent thunderstorm front in the direction of Hankmo, just as the Mavic's battery started to run out. Fortunately, there were spare batteries waiting on the ground. The tarphead clutch marveled at the udders sloshing from 120 meters away. After all, they didn't crash with the little Mavic :)

Lightning was known and the radar image was often marked, but when it comes to photographing birds in the field, it has been tamed to the point where cycling is not really enjoyable, especially far away. As the store slowed down, lightning flashed nicely behind the Zeppelin and finally a full turn and speeded home and even faster on the bike to the edge of the field next to Biltema. This time, I was able to use a mobile app to capture lightning, especially in the early evening. In the end, I had to stop and take the equipment home and go to the store there and then quickly return to the same p...

A nice thunderstorm developed in the Vaasa region to relieve the hot, sunny day. We were going to visit the Andromeda Meteorite and got stuck in the rain before the village of Sundom. There was quite a commotion when centimeter-sized hailstones started hitting the car in the middle of the heavy rain. When we got to Rii, we admired the incredibly bright cloud rays. From the same cloud, two bolts of lightning struck somewhere very close. After getting back to the city, we continued in the direction of Vöyr and Maksamaa. That's where the helicopter photos come from. I'll put a photo combo...
