Spring aurora borealis in a weak solar wind situation. The oval was currently rising almost to the zenith and the proton spots delighted with their existence. Otherwise, the usual aurora borealis, but a nice color scheme. The green color was clearly visible and from time to time the upper parts of the strands were colored in reddish tones. Some of the streamers also created pink bottoms for the northern lights.

The mass eruption of the corona allowed us to wait more, but since the polarity was mostly wrong in terms of the aurora borealis, there was no actual explosion in the sky. However, during the dark part of the night, a few very colorful sub-storms formed with red and blue hues. For a moment, red and purple threads were visible to the naked eye in addition to the green.

Again, the colorful aurora borealis typical of the season. The green was visible with my own eyes, the pink lower parts only in the brightest moments of the substorm, and the red upper parts were visible as gray with the eyes, clearly through the camera. After dark, 3 separate substorms formed. I stopped following around 01:00.

The launch vehicle's combustion gases, possibly aluminum oxide, glow high in the atmosphere. It is not known what event this is related to. The phenomenon was visible in the southern sky for about 10 minutes. #raketti: Yars-E

Typical for the season, the weak aurora borealis in the dark moment around midnight. The green color was weakly visible with the naked eye at times, the red and blue-refracting shades only with the camera.

The weak opening wind offered a great little set of substorms. During a couple of hours there were at least 4 clear substorms, where the oval opened like a zipper towards the pole and equatorial position, with bright strands and pink lower parts coloring the sky. Now is also the time of the blue aurora borealis at its best.

Proton aurora borealis in the southern sky. These are formed when the fast plasma of the substorm plunges into the inner magnetosphere. In the region of the ring current, the pre-existing cold and dense plasma reacts with the hot, kinetically energetic plasma to form EMIC waves. The EMIC waves then cause the protons to plunge into the upper atmosphere, and thus diffuse, slightly blue-refracting patches are formed in a significantly southern location compared to the normal oval. The light streak in the picture is, on the other hand, artificial light. #diffuusi

In many ways, very typical aurora borealis. The characteristics of the solar wind were acceptable, except the direction of the field put the brakes on as soon as possible. The northern lights in the picture were rather expressionless and only faintly visible with your own eyes. However, spring can already be seen here. The color gamut is like a rainbow, at least through the camera. Green is formed in the collisions of oxygen and energetic electrons at an altitude of about 100 km. Red is also formed from oxygen, now only the density of the gas is so low that it is possible to form red light alr...

The CME hit, the crescent moon and the clear frosty night offered a spectacle of its own. The color red was wonderful at times. Pakkanen was completely forgotten in the joy of filming. There aren't many nights like this in a year.

The weak CME component and the favorable Bz component coincided in time with a good seam. However, the show never improved much from this. A decent break in the plasma tail did not happen, and at best the broad oval slightly brightened in different places, offering green stringy shapes. There were indications of dune shapes, but they were only very marginally visible and I leave them unmarked. Could it be the low speed of the solar wind and thus the field lines did not experience enough pressure to enhance the reconnection. Below are a few pictures of diffuse and weakly stringy aurora borealis...

A calm aurora display in a dynamic but weakly negative Bz-influenced situation. According to the satellite data, there were indications of a weak CME. A few small brightenings occurred in the oval, but a large or aggressive electron rush did not come. The northern lights were mainly diffuse and very weakly visible to the naked eye. Green strands separated from time to time. The red glow in the upper atmosphere stood out only when seen on camera.

The situation in the early evening mainly offered a few distant small storms. After about 21:00, a diffuse arc appeared considerably further south and the growth phase of the substorm began. That's how the battery started beeping that power was needed. In the first picture this growth phase, in the second picture a distant momentary brightening of part of the arc, probably a small substorm.

Weak aurora substorm after a long time. However, it was nice to see at least a little aurora after a continuous cloudy season lasting about 3 months. The yellow spot of light in the picture is apparently a high-air flare related to Kajaani's aviation exercises. These flares are pyrotechnic mass and burn brightly for a few seconds. During the exercises, you can see several such yellowish spots of light.

After a long time, a brisk substorm in the afternoon made me happy in the direction of Valtimo. A substorm began to develop still during dusk. Around 1810 the plasma tail broke off creating a few minutes of fireworks. The proton spots separated a little before the substorm and a moment after. The red upper part also stood out over a few spots, hence the RAGDA designation for this one. Camera pictures still in summer time.

The first substorm of the evening, right after dark, offered a rare guest, mr. STEVE's. Later, very traditional and peppery substorms created dune villages and various shapes, but this time the other sub-auroral sets were out of reach, at least as far as I could see. All in all, a great set considering the miserable weather this season.

I chose the bright aurora borealis, because this substorm, from which the first photo was taken, was indeed a beautiful colorful set. The active phase lasted a few minutes. Otherwise, the oval was only visible as a faint area in between, forming green-refracting threads. The red color looked gray with my own eyes, so I don't check this. I followed for a while to see if the SAR arc or anything else interesting would appear, but not this time. The hazy weather and the half moon that appeared in the sky added to the challenge of seeing the dim phenomena associated with the aurora borealis.

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...

Again, a fast opening wind and a suitable Bz collapse in a dynamic situation provided an aggressive substorm. After the brightest glow ended in the recovery phase, a stringy region offering pink emission appeared again at the equatorial position. I'll mark this as steve again, basing my thoughts on the sub-auroral region emission and recovery phase situation. In the pictures, this pink emission and in the bottom picture the substorm in its brightest phase.

A slightly more atypical case when it comes to northern lights. During the recovery phase of a violent substorm, the so-called in the sub-auroral region, a stringy, pinkish, westward-progressing region appeared in the sub-auroral region, forming a strong STEVE for almost half an hour. I mark as steve, let the more knowledgeable correct the correct marking. Attached are a few pictures. The pictures are not in chronological order. #deeppurple
