Apparent Close Approaches of NEAs to the Stars for December 2023 Observatory C48 Sayan Solar Observatory, Irkutsk The list of apparent approaches of Near-Earth Asteroids to the UCAC4 catalog stars. Within some time span an asteroid moves near two stars so that the angular distance between the objects does not exceed some predefined value (in our case 30 arcseconds). The arcs of the spherical triangle sides being measured it's possible on the base of the catalog data to determine the coordinates of asteroid. The first line of the output data shows the number, name and vis.mag. span of asteroid. Other lines include the time span (UT), catalog numbers and visual magnitudes of stars. The magnitude difference between the objects usually is not more than 0.5.
