... For reliable estimation of the accuracy of asteroid CCD observations we usually consider from ten or more various NUMBERED MINOR PLANETS (NMPs) observed during several nigths per month (more then 50 positions). ... They can be considered as an indicator of accuracy of the CCD positional observations with given MPC code. ... For any NUMBERED minor planet the (O-C) values must be zero if the errors of observations and the errors of its theory are absent. ...

General Information . ... The conference is organized by the Sternberg Astronomical Institute (SAI) of Moscow University and the IAU Working group "Site-testing Instruments" . ... Use of site data in telescope operation and adaptive optics. ... Recent conferences on this subject (2007, 2008) demonstrated great interest of the community, hence the need for a new meeting. ... Unlike previous recent conferences, this meeting will cover all aspects of site monitoring for optical/IR astronomy. ...

... The circumnuclear GASEOUS disks are often decoupled from the circumnuclear stellar disks and are even stronger inclined to the outer disk planes; in fact, we have found a considerable `population' of inner polar rings. Inner gas polar rings are found as in spiral galaxies with the massive outer gas disks co-planar to the main symmetry planes (e.g. NGC 2841, Sil'chenko et al. 1997, and NGC 7217, Sil'chenko & Afanasiev 2000) as well in many lenticular galaxies (Fig. ...
