Abstract

Astrometric and multicolor photometric observations of near-Earth asteroids have been made at the SBG telescopes of the Kourovka Astronomical Observatory of the UrFU and the Zeiss-1000 telescope of the Simeiz Observatory in 2022–2023. Improved orbital elements were obtained for seven asteroids from astrometric observations at the SBG telescope. Axial rotation periods were estimated from photometric observations for seven asteroids. Color indices for six asteroids were obtained from photometric observations in B, V, R, and I filters.
