Preliminary reduction and analysis of the Bucarest Observatory photographic plates: Astrometry of asteroids (1931-1933)

چکیده
The Romanian Astronomical Plate Archive consists of 10550 plates of which 8169 are of ast roids observations. A total of 850 asteroids and 78 comets were observed in the 1930-2005 period. After a careful investigation of the whole plate archive we discovered that a series of observations were not capitalized, such as a set of minor planets which were observed during 1930-1955. The lack of accurate star catalogues containing positions and proper motions was one of the reasons why the fi nalization of the reductions was neglected in that period. Here we report 300 astrometric positions for 150 asteroids found on the oldest plates of the archive (1931-1933).

Improvements of astrometry from ground based observatories
The analysis of planetary satellites or asteroids ground based observations is quite similar. Our first goal was to improve the astrometric reduction for digitized photographic plates in case of too few reference stars and to propose solutions. We here present astrometric techniques used for old observations of the Galilean satellites made with the 26-inch refractor of USNO in Washington DC fro...
متن کاملNear-Earth Asteroids Data mining on Astronomical Databases: EuroNEAR experience
In the framework of EuroNEAR network several databases around the world were datamined. The main scientifi c objective was the astrometry of Near-Earth Asteroids (NEAs) for both precovery and secure orbits of these objects. The article presents few aspects of data-mining and the developed procedures for accomplishing these objectives. Introduction EuroNEAR is a network composed by both astronom...
متن کاملEURONEAR - Data Mining of Asteroids and Near Earth Asteroids
Besides new observations, mining old photographic plates and CCD image archives represents an opportunity to recover and secure newly discovered asteroids, also to improve the orbits of Near Earth Asteroids (NEAs), Potentially Hazardous Asteroids (PHAs) and Virtual Impactors (VIs). These are the main research aims of the EURONEAR network. As stated by the IAU, the vast collection of image archi...
متن کاملDigital Access to a Sky Century at Harvard. Ii: Initial Photometry and Astrometry
Digital Access to a Sky Century @ Harvard (DASCH) is a project to digitize the collection of ∼500,000 glass photographic plates held at Harvard College Observatory. The collection spans the time period from 1880 to 1985, during which time every point on the sky has been observed approximately 500 to 1000 times. In this paper we describe the results of the DASCH commissioning run, during which w...
متن کاملImpact of Hipparcos Data on Astrometric Reduction of Solar System Bodies
We investigated the improvement of photographic astrometric observations of solar system bodies by use of Hipparcos Catalogue stars, PPM Catalogue stars, and advanced plate reduction procedures. In the plate reductions, we rst computed apparent, topocentric coordinates of the date for the reference stars, taking into account eeects of refraction, aberration , precession, nutation, etc. In this ...
