 Distinguishing features of CCD astrometry of faint GEO objects
Report presented at 36th COSPAR Scientific Assembly Beijing, China, July 16-23 2006. Apex II is a general-purpose software platform for astronomical image processing, being developed at Pulkovo observatory

 Distinguishing Features of CCD Astrometry of Faint GEO Objects.
Preprint submitted to Advances in Space Research.
The problem of initial reduction of CCD observations of faint GEO objects is studied. Several difficulties and questions arising in connection with image processing for this kind of observations are mentioned. A natural way to apply the PSF fitting technique to line-shaped trails of stars or GEO objects is described and illustrated by its implementation in the Apex II astronomical image processing package. Logical filtering technique to improve the automatic object detection is proposed. These rather convenient and versatile methods can increase astrometric and, to a lesser degree, photometric accuracy of faint GEO object observations.

 Photometry of asteroids: detection of the YORP effect
We present results of photometric lightcurve observations of asteroids carried out with the goal to detect the Yarkovsky-O'Keefe-Radzievskii-Paddack (YORP) effect. For an irregularly shaped asteroid the YORP can change the rotation period and the pole direction [1, 2].

Dear Mr. Abalakin and Mr. Molotov,
thank you for your final report, I have approved it. Your project is a very good example of a cooperation between the teams from 4 different NIS countries. I also appreciate the wide output of your project which enable the consortium members to become active partners in the international scientific cooperation.
 
With best wishes,
