Rocket-related clouds - 29.3.2023 at 23.04 - 29.3.2023 at 23.12 Lieto Observation number 113916

Visibility IV / V

Matti Helin, Ursa (Länsi-Suomi)

One new phenomenon for yourself. An interesting sight. Like a comet, but quite fast. The freezing fog and light pollution were a bit of a hindrance, but the pictures were still ok.

It's strange to think that that incident was somewhere over a thousand (thousands) of kilometers away. And when you think about who sent it and for what purpose, well... It made me wish that it would explode in the middle of takeoff.

Well, unfortunately not.

The tip was followed by a couple of dim spots, most obviously remnants of earlier stages.

That in itself was an unnatural sight. For some reason, the song "Ten sticks on the board..." started playing in my mind.

      The rocket contrails are colorful clouds that appear when the sun is below the horizon. The contrails can float so high in the atmosphere that the sun shines on them even if it is already completely dark on the ground. They stay visible noticeable quite long after the launch.

      The colors are created by the scattering of sunlight in the small ice crystals. In Finland, rocket phenomena from two different locations have mainly been observed. One of them is the missile launches from the submarines from the White Sea and the Arctic Ocean. They use solid fuel that creates colorful clouds.

      Another source of rocket phenomena is the Plesetsk Cosmodrome Area in Russia. There are a few launches from there every year. These fires usually use liquid fuels, making the clouds less spectacular.

      The visibility of the rocket launch is affected by the time at which the launch is made and where the winds blow. The best of all is around 3-5 o'clock Finnish time, when the cloud has time to spread out a bit and shine in the morning sun coming from the east when it is still dark or dark in Finland.

      During the first decade of the 2000s, rocket phenomena have been observed about twice per year in Finland. Since then, however, it has been quieter.

Moraalisesti tämän hehkuttaminen on tosiaan vähän arvelluttavaa tässä maailmantilanteessa. Itse seurasin syksyllä venäläistä sivustoa, jolta näki valaisevien yöpilvien kehittymistä illan edetessä. Tiesi, mitä olisi täälläkin kohta tarjolla. Alkoi vaan jotenkin tuntua pahalta. Monta hyvää asiaa menee pilalle näissäikin merkeissä nykymeiningillä.

Timo, näin se valitettavasti on.
