Astro Autumn in Holosiiv


Hardly a sensation...

Seminar goes in Ukrainian

The mass media of Ukraine and the world reported that the scientists of the Main Astronomical Observatory of the National Academy of Sciences of Ukraine (MAO NASU) observed the Unidentified Atmospheric Phenomena (UAP, which is introduced instead of the previously used term UFO).

Information about these observations were published by Dr. Sci. B.E. Zhilyaev (MAO NASU), V.N. Petukhov (MAO NASU), and V.M. Reshetnyk (Taras Shevchenko National Universty of Kyiv) on the website of the scientific archive (arxiv.org/abs/2208.11215v2, 10.48550/arXiv.2208.11215) as a pre-publication. The observations of UAPs were conducted in the test mode during scheduled meteor observations and their results were not discussed and reviewed at the MAO NASU.

Because this paper and results have drawn a lot of attention and sometimes an inadequate reaction, we organized the Astrophysical Seminar of the MAO NASU on September 15, 2022, where one of the authors, Dr.Sci. B.E. Zhilyaev, reported about these observations, interpretation, and argumentation why the observed events are precisely UAPs. The results of the discussion were reported at the meeting of the Scientific Council of the MAO NASU. Members of the Scientific Council came to the following conclusion:
   - Observations conducted by B.Yu. Zhilyaev and his colleagues are original. But the processing and interpretation of results were performed at an inappropriate scientific level and with significant errors in determining distances to the observed objects. Also, the dates of observations are absent in the paper; the authors do not indicate which events were observed simultaneously from two sites; the authors do not provide arguments that natural phenomena or artificial objects of earthly origin may be among the observed UAPs (meteors; objects carried by the wind over long distances; space debris, artifacts, etc.).
   - Instead of a critical analysis of observations (possible errors, adequacy of models, accuracy in post-processing), the authors postulate unreasonable conclusions about the characteristics of the observed objects as UAPs.
   - The Scientific Council of the MAO NAS of Ukraine requests the authors to update the version of the article on the website of the relevant archive with the mandatory replacement of the sentence "The Main Astronomical Observatory of NAS of Ukraine conducts an independent study of UAP ..." to the phrase "The authors of this paper conduct an independent study of UAP ...".
   - The Scientific Council of the MAO of NASU believes that the information published in the aforementioned paper by B.E. Zhilyaev et al. was premature and did not meet the professional requirements for publication of the results of scientific research.

Main Astronomical Observatory NAS of Ukraine

Main Astronomical Observatory of NAS of Ukraine was founded July 17, 1944 on the initiative of famous scientist, astronomer and geophysicist O.Ya. Orlov (1880 - 1954). It is located 12 km from the center of Kyiv Holosiiv forest (hence its unofficial name - Holosiivska).

Observatory was headed by Acad. of USSR Academy of Sciences O.Ya.Orlov (1944 - 1948 and 1951 - 1952); Corresponding Member of USSR Academy of Sciences V.P. Tsesevych (1948 - 1951), Corresponding Member of USSR Academy of Sciences A.A. Yakovkin (1952 - 1959), Academician of UkSSR Academy of Sciences E.P. Fedorov (1959 - 1973), Ph.D. I.K. Koval (1973 - 1975). Since 1975 the Observatory of NAS of Ukraine has been headed by Academician of NAS of Ukraine Yaroslav Stepanovich Yatskiv.

Observatory takes a leading place in many areas of astronomy, such as the study of Earth's rotation and construction of coordinate systems in space, physics photosphere of the Sun and solar system formation and evolution of stars and galaxies, and others.

In the MAO the  Specialized Scientific Council for doctoral and master's theses in physics and mathematics works in the fields:

  • astrophysics, radio astronomy
  • heliophysics and physics of the solar system
  • remote aerospace research

GAO publishes magazines "Physics and Kinematics of Celestial Bodies", "Space science and technology" and the annual "Astronomical Calendar"

Achievements of Observatory scientists more than once won State awards and medals of the USSR and Ukraine in the field of science and technology, awards of NAS of Ukraine, the Cabinet of Ministers and the Verkhovna Rada of Ukraine, international awards, among them "Dr. Demyaniv Foundation. For peace and freedom of Ukraine" and EU Descartes Prize 2003, the medal named. Yuri Gagarin and the Order "For Merit".

In 2004, MAO was awarded by Certificate of Honor of the Cabinet of Ministers of Ukraine in connection with 60 - the anniversary of MAO, and the minor planet number 15675 was named "Holosyeyevo" in honor of Holosiivska Observatory.

The Observatory has eight academic departments: physics of stars and galaxies, astrometry and space geodynamics, physics of planetary systems, solar physics, physics of atmospheric optics and instrumentation as well as Astro/Space Information and Computing Centre (ASICC).





Moon craters were named after O.Ya.Orlov, A.O.Yakovkin, I.V.Gavrilov
