The positions of asteroids were calculated with the differential reduction method i...
Aims: Astrometric observations performed by the Gaia Follow-Up Network for Solar System Objects (Gaia-FUN-SSO) play a key role in ensuring that moving objects first detected by ESA's Gaia mission remain recoverable after their discovery. An observation campaign on the potentially hazardous asteroid (99 942) Apophis was conducted during the asteroid...
As a result of observations in 2008–2011 with the axial meridian circle of the Nikolaev Astronomical Observatory, we compiled two catalogs with a total of 284557 objects. We conducted a search for probable candidates for binary and multiple systems using the method checking differences between quasi-instantaneous and long-term proper motions for st...
On the base of CCD-observations made with the axial meridian circle of the Nikolaev Observatory from 2008 to 2009, we compiled a catalogue for astrometric positions and proper motions for 140321 stars located in an ecliptic zone and around high proper motion stars. The root-meansquare error for a star position is 20–65 mas in right ascension and 30...
A compiled catalogue of 21 440 stars with magnitudes between 10 and 17 is prepared from original observations made at the end of the 20th century to the beginning of the 21st century. The catalogue contains 227 fields of the celestial sphere centered at ICRF extragalactic radio sources with declinations of −17 to +89°. The field size is 40′ for bot...

At the IAU XXVI General Assembly in 2006, the Division I decided to
create the Working Group on Astrometry by Small Ground-Based Telescopes
(WG-ASGBT). Its scientific goals are to foster the follow-up of small
bodies detected by the large surveys including the NEOs; to set-up a
dedicated observation network for the follow-up of objects which will b...
We attempt to throw light upon the poorly known astronomical dynasty of Knorre and describe its contribution to astronomy. The founder of the dynasty, Ernst Christoph Friedrich Knorre (1759–1810), was born in Germany in 1759, and since 1802 he was a Professor of Mathematics at the Tartu University, and observer at its temporary observatory. He dete...
Regular positional observations of minor planets in Nikolaev Astronomical Observatory have been begun with installation of photographic Zone Astrograph in 1961. The observations of 19 selected minor planets up to 12 magnitude were obtained for 36 years. Accuracy of the photographic positions of minor planets is rather high, 0.15 0.19. These positio...
A compiled catalogue consisting of more than 22000 reference stars in the range of 10m 16m obtained with 235 fields of delta from -17° to +80° around extragalactic radio sources (ERS) selected from the ICRF list. Initial catalogues were obtained from photographic (PG) and CCD observations.
In 2004-2007, 560 observations of 17 Near-Earth Asteroids of 15-21 magnitudes were made at the Russian-Turkish telescope (RTT150). The reduction was made using reference stars from the UCAC2 and USNO-B1 catalogues. The comparison of the observed and calculated positions of the asteroids using the HORIZONS system gave standard errors of a single pos...
Asteroid masses are extremely important for the determination of their bulk densities, especially for the discussed relatively high porosities in about 20 to 30% of the studied bodies. The problem will have some coverage in clarifying errors of both mass and volume determinations. We have used lists of encounters for massive and less massive astero...
The Nikolaev Astronomical Observatory (NAO) was founded in 1821. In the initial ``naval'' time of its growth the observatory also carried out some works of an astronomical character. Later on, and especially in the last decades there have been finally formed two main directions of scientific activity at the NAO, as position determination for celest...
Modern astrometric projects require precise positional measurements of objects down to magnitude 20m-22m. For ground-based observations, this is possible by the use of astrographs with apertures 1 meter or more with precise tracking using long exposures and precise timing. The multi-functional astronomical complex RTT150 (the 1.5-m Russian--Turkish...
In extending the range of artificial and natural objects observed in near-Earth space to faint magnitudes both telescope parameters and detection methods are of great importance. Possibilities and list of problems which can be solved by the use of the AZT-8 with a CCD camera are considered. It is expected that position accuracy for near-Earth space...
Karl Friedrich Knorre (1801–1883) was the son of Ernst Knorre, an astronomy professor at Dorpat university. During his education at Dorpat university, he became acquainted with Wilhelm Struve, the future director of Pulkovo observatory. Because of Knorre's passion for astronomy, Struve recommended him to the post of director of the planned naval ob...

Computer control was introduced for the automation of all the major
operations of the Pulkovo horizontal meridian circle. This involves an
automatic setting system (mirror setting), a circle reading system, two
photoelectric eyepiece micrometers, meteorological data sensors and a
rotating drive of the pendulum horizon.
A new axial horizontal meridian circle is described which is designed to reduce the influence of systematic errors associated with conventional circles. The instrument constants are controlled continuously by means of marks in the prime vertical. A method for determining stellar coordinates using this instrument is developed.
The observations in R.A. with the Pulkovo HMC and investigations of the instrument, reported in Trans. IAU XIVA (p. 39), are being continued during the past two years (Pinigin, 1972, 1973). Some of the new results are as follows:

... otation velocity of the ICRF and DE200 systems as compared to the velocity derived from minor planet observations made by HIPPARCOS space satellite. The higher accuracy of the above mentioned parameters can be explained with longer observational period in 37 years of minor planets in Nikolaev than 3.5 years of observations with HIPPARCOS satellite.Aslan et al., 2004). The observations usually took place in the nights of good transparency and at least 5 days away from the full Moon (the mean number of clear nights is about 100 per year in Nikolaev). InTable 2, one can see summary statistics of CCD observations at ZA, where s a;d are external errors of a single (O–C), calculated for objects which hav ...

... There are 36 asteroids with their mass determined to better than 10% (including Vesta and Ceres that are presently observed by the Dawn mission, and some binary asteroids) distributed in several taxonomic classes. This number is slightly increased when complementing the Gaia observations by ground-based data for those close encounters that happen just before or after the mission (Hudkova et al., 2008). Good knowledge of their volume will be mandatory to derive reliable estimates of their bulk density and further indication of their porosity (personal communication). ...
