It was a great performance from west to east to zenith. Quite a few pictures were taken.

Noctilucent clouds visible between clouds

Pentti Arpalahti

This time there were almost stationary lower clouds in the sky. I went back and forth to the observation sites. It looked bad, but the north could still be checked from the sidelines. Fortunately, the cloud hole was just where the light line stood out. The back screen promised so much that I flicked the images as the light area brightened slightly and rose higher. The clouds were so weak that only in image processing was their essence confirmed. The modest show was on display for only twenty minutes with the nights below the lower clouds. Edit. I added an overview to mark the area where the ni...

Noctilucent clouds visible between clouds

Pentti Arpalahti

It was a whim that I had time to photograph the night clouds in the northwest. I used the opening in the lower clouds and raped the images when the brightest parts of the area were visible. I cleaned up a few clouds by combining two pictures taken in a row. Visually, only the brightest belt strips stood out. The image uses almost the entire Lightroom and Photoshop adjustment arsenal. As I set out to explore the northeast, clouds rolling from the southwest filled the sky. However, there were enough gaps in the clouds for a big play to be seen in the north-northeast.

The observation window now opens before midnight and continues beyond three in the morning and the night goes dark. Both bears, Cepheus and Cassiopeia, stood out from the second image even through the gauze clouds. All sorts of rude were fooling around. The brighter spots on the weave image ignited for a moment the unnecessary spark of hope. The north-northeast final check showed only small teeth at the edge of the distant cloud.

Eye-catching night shining clouds

Pentti Arpalahti

The first window observation was 0:44. Although there were lower clouds in front, there were so many gaps that the extent could be estimated at 3/8. One wide belt extended over the zenith. After one, the lower clouds covered almost the entire show and the north-northeast direction faded. Just to the west, the belt group peeked at the edge of the lower cloud raft and left the observation site. While editing the photos, I glanced out the window after two and had to go out again with a shorter lens. The lower clouds had completely disappeared and 3/4 of the sky was filled with a flat night cloud ...

The KH-like twisted chain was visible for three minutes. It seems that development began with loose pieces, the lower edges of which then merged together. The cover image of the rapeseed is the same as the square image. The pictures were taken: 1.27.11, 1.29.35, 1.30.07 and 1.30.51.

Conditions were almost as bad as the night before. An opening appeared in the northwest for a few minutes, after all, where an avalanche was found. The north direction started to open unnecessarily late, about a quarter over two. To the northeast, nothing was gleaned from the gaps in the clouds.

As holes in the abundant cloud cover tore at the last moments of the observation window, with the sun still seven degrees below the horizon, I pinched the field to slam the camera into brighter places. The lower clouds moved at a fair pace. Visually, no night clouds could be observed, but with severe handling, a few fish bones and perhaps even a belt strip appeared in the pictures. With a shutter speed of three seconds, the lower clouds went awry. The first image is from the northwest and the rest between the north and northeast. In conclusion, this is so poor that I put it through maintenance...

The atmosphere was special. The sky was completely cloudless. There was no gust of wind. There was no hustle and bustle of the weekend from the city, nor did the blackbird communicate the boundaries of its territories. As if the whole universe had stopped. The infinity of space could almost be felt on his skin. In the north, however, a very faint light strip stood out against the blue sky. The play brightened up just about half past two. Only the heavily modified images revealed the scope of the play.

Pentti Arpalahti

The one-and-a-half-hour unsuccessful trotting back and forth between observation sites the previous night was now credited. Before half as northeast of the lower clouds, dim belts were already lurking. To the north, then north-south curved belts formed, eventually extending over the zenith. There was also a separate belt area between southwest and west. The northern group just stumbled and brightened until it melted away as the first rays of dawn caught on the edges of the lower clouds. Fine and beautiful was the show. Edit. I changed the last image to a situation where day clouds take over fr...

After two, there was enough of a gap in the base clouds that you could go take a few certainty-for-a-sake pictures. The sky has been full of night after night. In the northwest, the clear belt of the partial magnification of the second image also stood out even with the eyes, but could not be sure whether it was just a contrast phenomenon. A few more weak streaks were found in the pictures.

Pentti Arpalahti

From the window opening to the northeast, a fine reddish arch was seen at eleven o'clock, and then a sudden departure came out in a light-skinned home outfit and some crunchy ones on the leg. Oddly enough, you can run like that. The cheeky afterglow spread from west to northeast. Whether it was now in some national landscape or on the high seas. When the sun was a couple of degrees below the horizon, twilight rays appeared: narrow high-definition and wide blurry. Edit. Phenomena changed to brown rays.

Shortly before one, the observation disadvantage was somewhat lower clouds, but they slid northeast quarter by one. After that, only a few submissions were a bit confusing. Due to the reddish color and hazy texture, there was no reason to suspect them as nocturnal. The sky is still very light. The youth practiced about one ball handling on the sports field in the light of the night sky.

The show began in the north cautiously between the clouds with a soft-edged and high-definition belt that immediately recognized it as night clouds. Gaps broke in the lower cloud layer and most of the clouds slid to the northeast. By half past two, even wide vortices developed into a diverse play. The avalanche groups extended all the way to the west. The main focus was on the northwest-north range.

It looked negative at first, but half past two in a perfectly clear part of the sky showed a hint of a lighter spot that was only visible for less than ten minutes towards the turn of the night. In the pictures, the structure of the spot stood out better.

The lower clouds disturbed the observation very badly. However, the thin fibers in the north stood out clearly to the naked eye below the cloud board. The lower clouds had a confusing rim-like border parallel to the fibers, but based on the fine structure of the bright fibers, they are not contrasting streaks. A dark cloud ferry flew from southwest to northeast and covered the possibly higher-rising Yökös. The comb-edged cloud also moved northeast, and no apparent contrast fibers could be identified. The observation window was open for less than 10 minutes.

The first observation was a narrow belt in the north next to the lower clouds at 0:40. The confusing furrows are in exactly that direction, but the belt in the elevator brightened and remained sharp. I switched to a better northeast opening place and there more gauze and avalanche groups appeared up to the zenith. After one, the cloud area slid to the northwest. The last solitary belt group in the west dissolved in the blue of the sky at 2:05, when the lower clouds were already beginning to turn red. At the beginning and end of the play, the height of the Sun was - 6 degrees.

Even though the water came to his neck properly, he was forced to photograph a handsome arch. As the sun went down, the color stripes dwindled, leaving only red. What was special was the handsome yellow-orange color of the Sun direction. However, nothing more special could be found on the sun side. Edit: I added two pictures of a possible zero-order glow. The white balance is daylight. Although the saturation and vibration adjustments are neutral, the color saturation is emphasized compared to visual perception.

Pentti Arpalahti

With the sun almost on the horizon, a narrow red arc appeared in the sky. The actual rain doesn’t seem to come from the sky, so I first interpreted it as a fog arc. The air was humid and even the ship's technology seemed to release moisture into the environment. I ended up in a rainbow when the removal of blue revealed a faint hint of a side arch. Clouds, on the other hand, often do their tricks. The triangular image is a combination of images taken at 18 mm focal lengths, the shape of which may not be quite perfect. The first and second images are aligned from the Kasimini images.

Excellent conditions would have been otherwise. but the sky is so bright that the night clouds should be very bright and settle to the west or east. Even the observation window is only open for more than an hour.

The lower clouds slightly obscured the night clouds, but they still stood out enough. From the photographs, the area was revealed to be wider than visual. I had to take pictures without a tripod from my hand with unnecessarily high sensitivity. The clouds were between north and northeast.

In Uppsala, a good group of night dwellers was seen in good conditions. I wrote the observation according to Finnish time. At 1:35 a.m., the clouds were clearly visible through the window. Local time from one the clouds were already fading from view in the morning sun.

A glance at the window showed a few thin strips and the opportunity to shoot outside was only a few minutes as the sky was soon almost completely covered. Conditions were awkward. There were lower clouds on several floors and the sky was open for a short time only in the northeast-east direction. Thanks to the northeast direction, it was worthwhile to perform polarization tests that would seem to support a positive interpretation. The first of the image pairs is normal and the second is through a polarizer.

No illuminating night clouds. There was some kind of roar in the sky. As the nights become brighter, light pollution no longer stains the sky and lower clouds, making identification difficult. The last image shows the northeast-east direction through the polarizer. The non-polarized cloud fiber clearly emerges.

Illuminated night clouds in the north. Pictures coming soon. Edit. In a characteristic way, the clouds came out dimly creeping. However, the light streaks stood out without dark edges, so they may not be contrasting stripes of dark cloud streaks. To the northeast, then, a sharp-edged belt stood out.

The conditions were pretty good. The very first glance at the sky came as a surprise. that the beginning of the season is so spectacular for itself. However, the clouds were too rough, dim, and the area extended too far south. To the east, the result of the second image polarization test was ruthless. The last hard-hitting image revealed the usual contrast lines on the horizon.

The predictions were promising, but there was little concern that the Evening Nine Burst seen in the bars would have passed in too bright a time. Then it began to happen: the first solitary ray gleamed at 23:47, in the northeast direction the sky began to glow and a handsome calm arc formed, followed by rays, spots and belts. It was great to watch the whole show in an environment where the only extra light was the echo of the sun.

It's a good thing when there are negative clouds in the observation program: observations are created as a series! Conditions were pretty good on the horizon and improved as the night progressed. Again, there was apparently a ghost spreading into the elevator in the sky. When the white balance of the images is daylight, then as the night darkens, the blue of the sky gradually turns orange to light pollution. Edit. Due to Mikko Peussa's excellent repo beam observation, I made repo adjustments for the last pair of pictures taken 1:27. A bit like greening, but in the northeast direction t...

Something appeared in the pictures taken just before and I left again with better equipment. The second time on the horizon, a frosted fiber rumbled, but to the north, there are often persistently abandoned furrows. The last image is like a star flight, the direction of which would suit the Aquariides of Halley’s comet, but it seems to be coming in the wrong direction between the Driver and Taurus. Otherwise, it was a great and gentle night and I no longer needed mittens.

It was always nice to check out the Z component when something seemed to happen in the sky. Edit. Title change: The northern lights stand out in the triangle image. Related to the subject of organic photography, I added a quad-image original that corresponds to visual perception.

The clouds slid quickly to the right and a splash of color was always visible in the sky at the same point when the cloud strip hit the spot. Figures 3 and 4 are unlimited images of the Lumia 640.

After midnight, leaving for the observation site in the north, a dim arc apparently separated from the previous display, and as soon as the camera was attached to the tripod, a two-part display began. The rays went out and the belts calmed down after 40 minutes. The active phase lasted from 0:21 to 1:00 (Figures 1 to 7). In case of SAR, I sifted around here and there, but no obvious arc came off the pictures. Edit. Before four, the Kumpula camera showed a clear arc and I was still checking the situation outside. I took the 8th picture at 3:37.

At the front door, I noticed a brighter glow above the ceilings than the standard light pollution. From the arm, even a gauze belt observation was immediately recovered, a quick pick-up of the pedestal from the hallway and a quick pace to the edge of the field and the show head started right away. At times, the brightening performance lasted more than half an hour. It wasn’t until the show faded that clouds began to pour i...

The first actual halo play of the year was quite nice. The 46-degree ring stood out on the horizon as a clear rainbow. The brightness of the pool side was also clearly distinctive. There is little reference to the horizon ring. It remains to be seen if anything comes off the materials in the stack. I guess Parry was hiding there. Edit. Interpretation of the "rainbow" based on simulation images as 46 degrees upside could be even more likely when the Sun was at 30.40 in Helsinki at 11.40. Edit2. The "rainbow" is thus a 46-degree pool side. No Parry was found in the stack. Edit3. The features of ...

The Nurmijärvi magnetometer again had a sharp plunge at the best time. Incidentally, the forecasts were not particularly promising. Edit. I added the curves of the Nurmijärvi magnetometer. The previous night was also active, but then I didn’t manage to make the observation myself.

Inspired by a bright evening and other pearl sightings, I went through the highest pimples in the nearby terrain and the pearl seemed to grab the cell. From the northwest there were dark norm clouds that covered the view to the west a little too early. In the last picture, magnified in the southwest, there is a confusing abyss, which was neither a pearl cloud nor a tail star crashing into the ground. The first image is a partial magnification of the slightly more processed vitos image.

Conditions in Helsinki are seldom favorable for artificial light pillars, but now the phenomenon could have been called the pillars of the whole sky. There is a whirlwind around the Hague. Small hits sparkled in the air and the pillars rose everywhere. The light source of the arched formation was probably the courtyard lights of The Hague Vocational School. The fine light poles would have been photographed no matter how long, but the focus of the lens froze like the graph - in 23-degree frost.

Binocular comet Catalina

Catalina approaches Arcturus. There was still enough distance to locate when the moon shone brightly and seeing was crappy. With Nikon's 7x50-Nikon binoculars, visual observation was not successful, but without monitoring, even on basic equipment, a dim spot was revealed. The first image is a stack of nine squares. Kakkonen is a single image that was better hit by Karhunvartija's two slightly brighter stars.

The long wait was rewarded with quite a play. There were gauze and belts from south to east and over the zenith. Sampu's 14 mm full cell had a very long glass. The show was over for an hour. Hard to say how much I lost from the start. I already got the first pictures when I stepped out the door. Went anywhere in the vicinity, so repos grabbed the cell in every direction. The air was clear and pungent, great conditions. Even three star flights flashed in the sky. I gleamed again at the fire of heaven for all the other passers-by. The young girl nearby seems to be saying to someone on her ce...

As the sun set on the clear sky, a rather pretty fan of twilight rays drew. The rays of the other party got better when you mixed the image with soft Light + 200R / 0G / B-200. The last number on the list is the height of the sun. Figure 1: 16:05, -5 degrees; Figure 2: 15:48, -4 degrees; Figure 3: 15:50, -4 degrees; Figure 4: processed Figure 3; Figures 5 and 6, 16:02, - 5 degrees Edit.

Glancing from the balcony, the sky glowed a magnificent moon 22r. With a terrible hössel out: the camera tangled, repeat the search and the wrong lens to change, where the keys ... after all, the tire shone steadily over an observation period of more than an hour and the images could be sifted in complete peace. From the balcony it was still visible 1:20.

When the Sun was about 3 degrees below the horizon, I tried that if twilight rays could be pulled out of the images, even if I couldn’t visually distinguish anything. The conditions just seemed favorable and something seems to show in the pictures. The shadow and backlash of the country attracted attention, which also became other reports from the SME region, but I was late for the best moment in filming. The rays of twilight did not detach, no matter how torn. Correspondingly, more dust spots were found in the cell.

Visibility at sea was otherwise good. The orbit stood out wide and the stars shone steady like small LEDs, but the ship’s smoke, water vapor, and lights clouded the northern horizon. The pulsating wind and vibration of the deck made it more difficult for several seconds of hand exposures as the arc of northern lights appeared under the paws of the Big Bear. The tripod, of course, was in the cabin when you just had to go take a look at the scene. Edit. Location failed at shooting time. The ship had left Helsinki at 5.30 pm.

The air was clear and the oval bulged south, so I had to go to the edge of the field to swell. Nurmijärvi drew a gentle curve upwards, but at ten o'clock there was a twitch downwards. There was a greenish streak on the horizon of Kumpula, and in the cameras of the north, belts struck across the sky. It took just over 12 minutes from the screen. Visually, with the help of the imagination, one could see faint variations in brightness above the ceilings.

When a green arch appeared in Kumpula's camera, there was a rush. Kaari picked up just the best to get on the field. The rays were quite visible despite the surface and cloud gauze. Once again, the active quarter-hour period correlates nicely with the Nurmijärvi magnetometer.

The air was otherwise cloudless, but at the beginning of the observation period there was so much fog on the ground that no reliable observation could have been obtained from the dim arc alone. Visually, the variations in brightness were very suggestive. All you had to do was shoot the camera instinctively in case you were lucky enough to shoot at the right moment. As the rays appeared, Nurmijärvi's Z-component began to decline, which favors an otherwise uncertain interpretation of northern lights. The pictures were taken at 0:43, 0:42, 0:54, 1:03 Edit.

Just as I mounted the camera on a tripod on Paloheinä Hill, a calm arch appeared. The belt soon became more vibrant and began to splash rays. There were two distinct highlights in the show. At the beginning, what was special was the red lower edge of the belt, which was clearly visible for about a minute and bounced out of the photo. There seems to be a yellow area between the red and green edges. The blue tips of the rays could not be distinguished. The show itself was not very bright, but thanks to the lighting of the tolerable environment, even the mere eyes could see something.

After one night, a very marginal observation was still successful, mainly for statistical needs. In the northwest, below the cloud board, a piece of the opaque belt split. Except for this small hole, the sky was covered with clouds. The obscure images are tight dents from the frames taken with the 14-millimeter. In the north, based on the northern lights cameras, there were still pretty good performances going on.

When a clear belt was visible in Kumpula's camera, he had to run suddenly to the edge of the field. The belt was clearly visible and dragged into the elevator towards Ottawa. Then I sprinted to Aino Ackte's park for a slightly better landscape. The huh belt was still visible. There was a hint like radii from the pictures, but not quite to mention. I made various reports about this and the much dilute show after 9pm. There might also be an activity at midnight, but I missed it.

It was a difficult and cool case of observation. There was something gleaming over the roofs from 0:50. There were gauze clouds in front, lit by a half moon. The calm arc was still recognizable on the camera screen. Eventually, after an hour of waiting, the 1:50 arc seemed to rise and brighten. The rays are also poorly distinguished in the images, but they could not be detected visually. The more active phase lasted five minutes, after which the belt dimmed. The downward inclination of the Z-component of the Nurmijärvi magnetometer clearly correlates with the activity of the belt.

The eclipse observation went awry. Even the localization of the moon was not successful at first, as the clouds occasionally revealed gaps lasting only a few seconds. The first image was taken from the cloud gap 4.06.34, when the moon was completely in half shadow. After that, the clouds finally condensed and the moon disappeared completely from view as it dimmed. The second picture was taken at 3.50.43, when the moon was already on its way to half shadow.

In the autumn of 2015, during the Perseidi swarm, we accidentally shot the same meteor with Pentti Arpalahti at a distance of about 12 kilometers from each other in Paloheinä, Vantaa, and Röylä, Espoo. Looking at the images, attention was drawn to the clearly observable parallax, which provided an opportunity to try to reconstruct the orbit of the meteor. The azimuth of the observed ignition and extinction points of the meteor and the determination of the altitude coordinates for each observation site were straightforward using star map software because the observation time and the coordinates...

When I left, I switched from 14m to Samyang's 50m. From the hazy garden, I also changed the location of the northern lights to the edge of the artificial turf field. Then a little bit of luck, small particles from the Sun and a little chunk were needed to drop into the atmosphere. Edit. In the second image, I first try to bring out the dim parts of the track as well, but as a result I lost the brightness variation of the bright part, which was more visible in the original.

Through the hazy sky, a belt show lasting about 10 minutes was first revealed. After that, high dim rays appeared, but hardly those proton arcs. After half past twelve, there seemed to be some reddish flutter, but from the pictures it was not certain if it was just cloud gauze. It was a funny incident when a couple walking in the evening asked, "What are you describing?" I replied, "I'm trying to make northern lights here, but there's nothing visible through Tommonen's fog ... what was that? .. they're northern lights!" The show really started almost immediately.

It did take a standstill when the oval glowed red, but the sky was before eleven in the morning. There seemed to be some flicker in the clouds, but nothing suggesting a repo came off the images. However, the sky became completely clear at three o'clock and the cell was able to catch a calm belt. Didn't get stuck anymore.

When Emma rushed out in the sky, they had to leave halfway to one field again, if there was still some leftover from the show. A very dim haze rumbled on the horizon and the full moon waved straight south. 0:43 However, the arch refreshed into a guard and the blasts could somehow be distinguished by the eyes.

Paloheinä Hill is a relatively good place to observe, as it is surrounded by a park, the forest of the central park and the lighting in the surrounding area is a bit more subdued. When Swan was in zenith, I started collecting squares for the stack from the area of the big rupture. Then the nice thing happened that while looking up at the sky and the meteor rumbled, the camera shutter was suitably open and the camera had a 7.5 millimeter glass.
