Abstract:
We continued our series of CCD observations of double and multiple
stars during 2019 and 2020. A total of 331 pairs were observed at two
stations, Serbian Astronomical Station on the mountain of Vidojevica
(ASV) and Bulgarian National Astronomical Observatory at Rozhen
(NAOR). They were performed using two telescopes, 1.4m at ASV, and 2m
at NAOR, and on them cameras of the same type, Andor iKon-L, are
mounted. Here we give 382 relative coordinates for 331 pairs, because
some pairs have measurements for several epochs or some pairs were
measured at both stations. Out of this number, 18 pairs have
calculated orbital elements and 11 pairs have calculated linear
elements. For these pairs the residuals are given. The smallest
measured separation is 1.25, and the largest is 120.65 for pair AC of
multiple star WDS00057+4549=STT547. Four new pairs are also presented.
