The northern lights of May Day touch the statistics.

This is the latest time in the spring to see the northern lights so north. The skyline to the north was already really bright, but in the west-southwest the northern lights still stood out nicely bright against the dark blue sky.

There were several bright nights in a row, but even weak repos couldn’t be caught, even though the Z component dropped promisingly. In the end, you ripped. In the first picture, there was a swirl of smoke, which I zoomed into the second picture, perhaps left by the wind. Even a few rays flickered funny at the street lamp. There are additional reddish reflections on the left side of the left street lamp.

The surprisingly beautiful and seasonally colorful sub-storm happened to hit at just the right time around 0100. The spring sky is already pale from the north, even at the darkest moment. The upper atmosphere is ionized in terms of nitrogen, so the blue color is strongly present.

I was going to rush to the beach when I started to look by the gauges that there could be repos. The latter are taken here when, at one time at night, reddish sunlight is seen on the horizon under an arc of northern lights. For a while the northern lights were really bright and the green was seen with my own eyes. As the storm's recovery phase began, a peculiar red west appeared in front of the arc northwest, lasted a few minutes, and disappeared. 1.09 is displayed and has already been lost at 1.14. I was still watching, although there were no major events in the arc in addition to the cho...

The satellite data showed the promise of possible northern lights. There were no dizzying readings at all and when it came to the night between Sunday and Monday, I left the use to the camera account. I set the timer to start at 0.20 and after about twenty minutes I had seen a very modest repo curl for ten minutes. No problem even though this set was not seen live :)

One could take that Independence Day worse than in the glow of the northern lights. The substorm remained a bit low, but the chorus waves in the recovery phase were spectacular.

I heard from a friend that repos were visible so I decided to go see it myself. They were low, but they were visible anyway. I had an hour to observe before they faded.

With the values still high, I had to go see what was visible. And you saw them. The ice mist made everything a little finer, almost art from pictures. Pretty storm again. Extra red display.

With Kytis again, when the values seem reasonable. The cloudiness is a bit of a nuisance again, but luckily just as the pretty storm started, the clouds understood to dodge. A nice addition was made by a single bright pillar of artificial light rising from the army area to the west. The specialty of the night this time was the greenish west / arc section above the arc of northern lights at the northwest at 1.59. Not before or after. The arc of northern lights faded shortly thereafter, sinking low into the light pollution / cloudiness.

Kytis again when the values are quite comfortable. The clouds just bothered most of the time. Images taken shortly before ten are likely to show the SAR arc, even partially covered by clouds. At half past eleven, a peculiar "color phenomenon" appeared in the pictures. At the western end of the arc, clearly outside the red area, was a clear pink area. I was even wondering if Steve could be? The color did not resemble a red or purple top but quite a clear white-pink! Through the night, the clouds eased, but so did the northern lights.

I went to the switch because the repo values were reasonable and it was likely that a substorm or pair would show up and it was also clear. When I got the camera focused, a diffuse arc appeared over the arc of northern lights and it was visible from about 10:16 pm to 10:26 pm (part of the time to the eye, the rest to the camera). Meanwhile, beneath the diffuse, turquoise green arc was marked by a small, pretty substorm. As the arc faded away, the recovery phase of the storm began and beautiful red rays rose into the sky for a moment. The arc of northern lights survived in the sky for several h...

The actual storm was left behind the clouds the night before, and I tried to capture the remnants of the eruption by taking a few pictures whenever Nurmijärvi's z-value dropped. Half past one of the lonely dim dimmer rays then flashed north. The second image ten minutes later is a reference to the fact that, at least not all the time, some floodlight was slamming into the sky.

I knew CME hit / hit the earth’s magnetic ring, so I set off as soon as the clouds gave up. The first pictures were taken from Pakkanenlahti, on the way to Sarviniemi (Taipalsaari). The first picture here shows how the clouds were still disturbing and the first storm didn’t really show up here properly. I "fortified" the north shore of Sarviniemi and waited for more. At the same time, the sky gradually became clearer. All the while in the sky the moon dimming activity was visible in the low north and on the lands of one side the arc rose high and for a while the dunes were faintly visible even...

The guy put a message that repos were visible, so I had to go see it. Pretty sub storm right at the beginning and then a few smaller. Nice that it was clear even though there was some moisture in the air. I don't know if the SAR arc is visible in a few pictures, I'll leave it to the jury to decide. A little faintly visible. A red glow was visible above the northern lights almost all the time. In the two countries at night began a calm phase of irradiation (last picture)

I used the northern lights, I couldn't wait, but still that best eruption surprised me. It was a comet to watch. There were whites and light purples before, that's where they started. One or two ago in the zenith, and I wasn’t quite in the open, I had come to my backyard a bit earlier. Fortunately, however, I still got out despite the toes pinching. During the night, the frost reading was at -7.2 at its lowest, and the rather cold one was at the top, where I started this bonga. The beautiful light purple and white appeared dim for probably almost an hour. This Korona phase probably too...

The values were already high in the afternoon. When the sky then began to darken, I took Osmo Action to the roof to be on duty. The extent of its image area is likely to be lost to those of Gopron. Even now, the activity seems to have been outside the picture in every direction. The direction of filming was somewhere with the cries of zenith. Quite a bit of green porridge seems to have boiled. Pictured is a taste of the fiercest boiling. Events in Juutuupi between 22.45-03.30. https://youtu.be/I7azlhokYVw

Northern lights that lasted all night appeared in the sky as the evening darkened into night. The night sky is no longer completely dark at this time of year, so the contrast between the repos and the background sky wasn’t quite what one might have expected: the northern lights looked a little modest. The northern lights activity was visible until dusk and probably continued until the early hours of the morning. Here are a few pictures of the best moments, the last couple of pictures are already at dusk.
