The project aims to solve a specific problem, namely the determination of the orbital parameters of meteoroids - small bodies that are the destruction products of asteroids and comets, as well as the study of complexes that form these bodies. Light curves and color indices are a source of information about the composition and size of the bodies of meteoroid flows, which are very important for assessing the degree of potential destruction that can happen after their collision with the Earth. popup.description2  The aim of this study was to obtain high-precision positional and photometric data on meteoroids, meteor streams, and their associated parent bodies using optical and radio observations. Based on optical observations conducted with a two-telescope complex during 2022–2024, a dataset of 1801 meteor registrations was created. Using this dataset, 124 pairs of meteor light curves observed simultaneously in two filters were obtained, allowing for the determination of the B-R color index in the BP/RP system of the Gaia EDR3 catalog and the Johnson system, calibrated to standard synthetic BVR magnitudes with an error of (0.2–0.3) mag. Radio observations of meteors were conducted using the M-FM network with two stations located in Mykolaiv and Voznesensk (Mykolaiv region) and the M-GRAVES network with two stations in Ivano-Frankove. The results of radio observations of the Perseids and Geminids meteor showers in August and December 2023 were submitted for publication on the RMOB website. During 2022–2024, regular observations of near-Earth asteroids (NEAs), including potentially hazardous and newly discovered objects, were carried out. As a result, a catalog of 1142 topocentric positions of 52 NEAs, which may be potential parent bodies of meteor streams, was compiled. The apparent magnitudes of these objects range from (11–16) mag. The catalog was created based on observations conducted at RI “MAO” using the FRT telescope and the KT-50 telescope of the Mobitel complex. The cataloged positions were submitted to the Minor Planet Center of the International Astronomical Union and published in MPC circulars. Software was developed and improved for automating observation processes, data processing, and analysis. As a result of this work, four certificates of copyright registration were obtained. The research results were presented at Ukrainian and international conferences, 4 articles were published in journals indexed in the Scopus and WoS databases with a quartile of Q1–Q2.
