Essay

The thesis is devoted to research of the positional and photometric characteristics of asteroids observed in frame of the Photographic Survey of the Northern Sky (FON). These characteristics are evaluated after digitization and reduction processing of scanned images of the FON astronegatives as a part of the Joint Digitized Archive of the Ukrainian Virtual Observatory. An analytical approach to searching for images of the Solar System small bodies is proposed. It is based on the analysis of ephemeris data generated by online Internet services at the time of observation and the calculated equatorial coordinates of all recorded celestial objects on the astroplates. Based on the results of applying these methods to the FON observational data, the three catalogs were elaborated and created, numbering 7289 positions and B-magnitudes of mainly asteroids and some comets. The accuracy of the obtained data was investigated, which is high enough for positional observations, but cannot be compared with CCD observations, radar or space observations of asteroids. Additionally, all positional data of asteroids that were previously obtained by classical observation processing techniques have been collected and systematized. This data refers to mostly bright asteroids that were observed in 1952–1996 within the framework of the ORBIT project at the Main Astronomical Observatory of the National Academy of Sciences of Ukraine. Some of them were updated by re-processing observations of asteroids with modern star catalogs, which made it possible not only to improve the positional accuracy for them, but also to correctly compare all series of asteroid observations provided at the Main Astronomical Observatory of the National Academy of Sciences of Ukraine.
