We introduce our efforts to monitor objects in orbit using astronomical observation data. Accurately and comprehensively monitoring the orbits of artificial objects such as space debris is essential for satellite operations and sustainable space development. To this end, we are conducting collaborative research to detect artificial objects observed in the all-sky survey conducted by the University of Tokyo's wide-field optical video camera, Tomo-e Gozen. We estimate the orbits of the detected objects and provide the data in standard formats such as TLE and OMM. In the all-sky survey by Tomo-e Gozen, approximately 900 moving objects are observed per night, about half of which are uncatalogued. This indicates that leveraging wide-field video observations may improve comprehensiveness through the discovery of uncatalogued artificial objects and enhance accuracy through optical observations. In this presentation, we report on the characteristics of artificial objects observed by Tomo-e Gozen and the orbital data obtained through this initiative.
