“…At the Pulkovo Observatory observations were carried out from December 8-12, 2009 with the MTM 500M meniscus telescope (Kul ish et al, 2009) mounted on the territory of the Kislo vodsk solar station of the Central Astronomical Obser vatory of the Russian Academy of Sciences (CAO RAS), as well as with the ZA 320M mirror astrograph (Devyatkin et al, 2004;Devyatkin et al, 2009) from December 16-21, 2009. The astrometric and photo metric processing of the 2009 WZ104 asteroid obser vations was performed using the APEX II software system (Devyatkin et al, 2007;2010). The astrometric positions of the object were obtained in the USNO B1.0 and UCAC3 systems of catalogs.…”

The astrometric and photometric observations of the potentially hazardous 2009 WZ104 asteroid were carried out at the MTM 500M and ZA 320M automatic telescopes of the Pulkovo Observatory in December 2009. A total of 686 observations were performed in the integral band and 146 observations with B, V, R, and I filters on an arc of the orbit of 17°; these accounted for about 77% of all worldwide observations (http://www.minorplanetcenter.org/iau/ECS/MPCOBS/MPCOBS.html).On the basis of the obtained data, the orbit was improved and an estimation of the physical parameters of the asteroid was made. Estimates of the absolute stellar magnitude of the asteroid, H = (20.52 ± 0.04) m , as well as its size and mass, were obtained. The taxonomic class of the 2009 WZ104 asteroid (R or Q) was determined. A frequency analysis of the series of observations was carried out; periodicities in the asteroid's light variation were revealed using this method.

“…Pulkovo observatory accepts in it active participation. Also Pulkovo observatory take a confident place in the first twenty stations (within 700 ones) among the observations of the NEO -objects [1]. The Laboratory of Astrometry and Stellar Astronomy fulfils the observations of wide double stars, planets with their satellites and also comets and asteroids using the normal astrograph (D=330 mm F =3500 mm, with CCD camera: S2C, FOV = 18x16 arcmin, pixel size 900x900 mas) and 65 cm refractor which has been equipped in 2007 with the CCD camera FLI Pro Line 09000 (FOV =12x12 arcmin).…”

In the Pulkovo observatory the observations of the Solar system objects and improvement of the processing methods are performing. EPOS (Ephemeris Program for Objects of the Solar system) is the effective math-soft application for study and ephemeris support of observations of such objects. There are the options in EPOS for calculation of the orbits of asteroids including NEAs and using the observations at the relatively short arc.Also we would like to present shortly our method of Apparent Motion Parameters (AMP) for determinations of orbits of artificial satellites and other objects from observations of short arc. The research program of the Orbital Stellar Stereoscopic Observatory (OSSO) is based on the stereoscopic method of observation for fundamental studies in the area of Celestial Mechanics, Asteroid and Comet Impact Hazard, Stellar Astronomy,Astrometry and Astrophysics with the magnitude of the target objects ranging from 8 m to 25 m . This project is designing for stellar-like objects observations, including the main types of the Solar system bodies.

“…4 In our knowledge there is no exhaustive statistics at this moment in the World (in general, and in Europe in particular) for NEAs activities. Astrometry of NEAs is also performed in Russia (Devyatkin et al 2007), and jointly in Turkey and the Ukraine (Ivantsov et al 2008), but their programs are not formalized with specific names.…”

Context. The EUROpean Near Earth Asteroid Research (EURONEAR) is a network which envisions to bring some European contributions into the general context traced by the Spaceguard Foundation which was carried out during the last 15 years mainly by the US with some modest European and amateur contributions. Aims. The number of known near Earth asteroids (NEAs) and potentially hazardous asteroids (PHAs) has increased tremendously, mainly thanks to five major surveys all focused on the discovery of new bodies. But also other facilities are required to follow-up and improvement the orbital parameters and to study the physical properties of the known bodies. These goals are better achieved by a co-ordinated network such as EURONEAR. Methods. Astrometry is mandatory in order to acquire the positional information necessary to define and improve orbits of NEAs and PHAs and to study their trajectories through the solar system, especially in the vicinity of Earth. Photometry is required to derive some physical information about NEAs and PHAs. In order to achieve these objectives, the main method of research of the EURONEAR is the follow-up programme of objects selected by a few criteria, carried out mostly at 1 m-class telescopes endowed with medium and large field cameras. Results. 162 NEAs summing more than 1500 individual positions were observed for a total time of 55 nights in both visiting mode and regular runs using nine telescopes located in four countries. The observations were reduced promptly and reported to the Minor Planet Centre (MPC) which validated and included them in the MPC and NEODyS databases following the improvement of their orbital elements. For one binary NEA we acquired photometry and were able to determine its orbital and rotational periods. Complementary to the follow-up work, as many as 500 unknown moving objects consistent with new Main Belt asteroids and one possible NEA were discovered in the analyzed fields. Conclusions. Our positions present 1 precision with an accuracy of 0.2-0.4 , sufficient for achieving our immediate main goals. The observations and data reduction were conducted by our network members, which included some students and amateurs supervised by professional astronomers. In most cases, we increased the observational arcs decreasing the uncertainties in the orbits, while in some cases the new positions allowed us to recover some bodies endangered to be lost, defining their orbits.
