Abstract

In this paper, we present the results of CCD observations of double and multiple stars conducted during the period 2021–2024. These observations were carried out using the 2-m telescope at the Bulgarian National Astronomical Observatory at Rozhen (NAOR), equipped with an Andor iKon-L CCD camera. A total of 302 relative position measurements was obtained for 228 double and multiple star systems, with some systems observed over multiple epochs. Among these, 34 pairs have calculated orbital elements, and 3 pairs have linear solutions. For all these systems, the observed minus calculated (O–C) residuals are provided. The smallest measured separation was 100 . 44, observed in the pair WDS 14376+2809 = COU 405, while the largest separation was 900 . 90, recorded for the pair WDS 21596+2453 = POU 5602.
