Contribution to the establishment of local reference frames around ICRF optical sources
Abstract
At Bucharest Observatory we started an observational program aiming the improvement of positions for optical counterparts of ICRF radiosources by narrow-field CCD observations carried out in Belogradchik Observatory, Bulgaria (43°37'36''E, 22°40'06'' N) using the 60-cm telescope. First results are presented in this paper.
