Rocket-related clouds - 9.9.2021 at 23.00 - 9.9.2021 at 23.05 Kuusamo Observation number 101164

Visibility V / V

I was filming the stars when I suddenly spotted this rocket in the sky. The rocket ran northeast toward North Repu, digging another lens that happened to be 70-200mm. For I managed to get this one box. 96mm and 13s, none grooved. Is there any fuel residue in the picture?

    • Very small area
  • Rocket launch
    • Barium cloud info

      Barium clouds have very rarely been seen in the sky during rocket launches. Typically a space organization has done an experiment in which a barium cloud is released into the upper atmosphere.


    • Rocket contrails info

      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.

Hieno kuva. Mitähän nuo takana olevat viirut tosiaan ovat? Osia aikaisemmasta vaiheesta?

Rayann Elzeinin videossa näkyy koko matkan perässä lentävän kaksi "satelliittia"

Riku, kiitos selvennyksestä.

Kyllä ne varmaan jotain aikaisemman vaiheen osia ovat, suunta ja nopeus on sama raketin kanssa, ja näyttävät pyörivän.

Ok ???? hieno ja ainutlaatuinen  hetki joka tapauksessa.

Näin tämän itsekin Posiolla erämaassa, oli kyllä erittäin näyttävä ilmiö.
