Provision for fulfilment of the projects in the frame of the international scientific programme "Astronomy in Elbrus region 2021 - 2025 yrs." popup.description2 Object: Solar System bodies targeted by international missions (asteroids, comets, satellites of giant planets) and selected stars, the interstellar medium, GRBs, and other transients. Aim: high-precision data and ground support for missions. Methods: photometry, spectroscopy, polarimetry, astrometry. Key results: Instrument upgrade—an additional photometer on the 200-mm guide of the 2-m facility enables independent photometry. Astrometric/photometric/spectroscopic/polarimetric data for ~100 asteroids and comets were transmitted to the Minor Planet Center (USA). Ground support provided for Lucy, DART, Psyche, and Gaia. Rotation periods: (21900) Orus 13.4798±0.0031 h; 4660 Nereus 15.182775±0.000058 h. Unique observations of (65803) Didymos during and after DART’s impact on Dimorphos. Joint polarimetric studies of Europa with HST and Juno. Under “Astronomy in the Elbrus Region, 2021–2025,” data obtained on transients, GRB afterglows, variable stars, the lunar exosphere, Uranus, stars with exocometary activity, a pulsator, and O–B stars. Polarimetry of NEA 2010 XC15 (rare E-type): geometric albedo p_v=0.38, D=0.11 km. For NEA 25330 (1999 KV4), with exceptionally high polarization at large phase angles: phase-curve parameters, p_v=0.018, D=4.45 km. Implementation/significance: Results are in use across the workflow and aid astronomical institutions and mission coordination centers. Despite frequent launches, ground support is vital to refine orbits and physical properties. In 2022–2024, Terskol Peak Observatory (code B18) achieved 0.05″–0.5″ accuracy; datasets were sent to the MPC and published in the MPS. Keywords: asteroids; observations; photometry; polarimetry; spectroscopy; space missions. Product Description popup.authors Larysa Karpova Vira Godunova Volodymyr Kozlov Andreev Maksym V.
