Accuracy of this observations is near 0.1 arcsec for objects which brighter 18 m. Values of angles of orientation between coordinate systems of ICRF and USNO-A2.0 and preliminary values of orientation angles between radio system of ICRF and optical systems of catalogues ERLcat and AMC are obtained. The astrometric software considering the imperfections of similar software have been created. 137 time differences UTO(X)-UTC are obtained. The investigations of magnitude dependence of Zeiss astrograph are finished. Comet C/2001 LINEAR A2 was observed at the Zeiss astrograph and reflector AZT-8. 74 precision positions of this comet are obtained. The catalogue and atlas of light curves of comets and catalogue of cometary brightness outbursts have been supplemented by new data. The investigation of observations obtained at the Kharkov meridian circle at eighth decade of past century have been continued. The catalogue by Glize have been supplemented by positions of stars at epoch J2000 and new values of proper motions and parallaxes. Product Description popup.authors popup.nrat_date 2020-04-02 Close
