S. Chernykh at the Crimean Astrophysical Observatory. The birth of the settlement of Nauchnyj coincides with the construction of the Crimean Astrophysical Observatory in central Crimea in 1945. The contributions of the observatory to the world of astrophysics are well known, and the name is being proposed on the occasion of the community's sixtieth anniversary.
