Observing programs of the Kyiv meridian axial circle equipped with a CCD micrometer

Abstract

Abstract. The present status of the Kyiv meridian axial circle after its refurbishment is described. The mounting of a new micrometer with the front-illuminated CCD 1040×1160 allows to observe stars up to V = 16 mag. For the stars of 11-14 mag, the internal positional accuracy of a single observation is 0.05-0.10 , and stellar V values are determined with an accuracy of 0.03-0.06 mag. The project of observations of star fields in the direction of 209 extragalactic radio-sources in declination zone 0+30 • is now in progress. The catalogue of positions, magnitudes and proper motions of secondary reference stars in regions with ICRF sources is expected to be compiled by 2003. Another project under way is a long-term astrometric survey of the equatorial zone to extend the Hipparcos-Tycho frame to fainter stars, and to measure their magnitudes and V − R colours.

“…Vertypolokh at Kiev reports that the meridian axial circle (MAC; 180/2300mm) was furnished with the CCD-micrometer (based on CCD ISD017AP, 1040 x 1160 pix), allowing to observe in stare and drift-scanning modes, and was put into operation at the Main Astronomical Observatory in 2001 (Telnyuk-Adamchuk et al 2002).…”

The Kyiv Meridian Axial Circle catalogue of stars in fields with extragalactic radio sources

“…The Meridian Axial Circle (MAC, D = 180 mm, F = 2.3 m) in Kiev was recently modernized by installing a 1040 × 1160 CCD camera that can work in scan mode (Telnyuk-Adamchuk et al 2002;Karbovsky 2004). The camera, designed at the Nikolaev Observatory (Ukraine), incorporates a glass filter to enable observations in the V band.…”
