Main actors in astronomy research in the country  There are 7 Research Institutes in the structure of the National Academy of Sciences of Ukraine (NAS of Ukraine), 2 Research Institutes in the structure of the Ministry of Education and Science, Youth and Sport of Ukraine (MESYS of Ukraine); 15 astronomical observatories and Departments in the structure of the Universities of the MESYS of Ukraine; 1 Private Astronomical Observatory play a main role in the development and teaching Astronomy in Ukraine.
The XPM Catalog  Absolute proper motions of 280 million stars distributed all over the sky without gaps in the magnitude range 10m < V <20m on the basis of combined data from 2MASS and USNO-A2.0 catalogues.
MAO NASU Plate Archive   Digital archive of MAO NAS of Ukraine (GPA) comprises data of about 26 thousands of direct photographic plates, obtained with 14 instruments in 9 observational sites, and more than 2000 digital images of different resolution available via GPA search pages.
Mykolaiv AO Plate Archive   Digital archive of Mykolaiv Aastronomical Observatory (MykAO) includes astronomical data obtained during observations with photo plates and CCD frames. The digitization of the archive is near its completion. Digitized images are available via a web browser and Aladin.
AO LNU Plate Archive   Astronomical Observatory of Lviv National University (AO LNU) is the owner of valuable archive that stores approximately 8 000 of photographic plates from 1939, including nearly 6 000 direct images of the northern sky. The archive is partly digitized and images are available via the joint search pages of AO LNU and MAO NASU.
IRA UTR-2 catalogue of RS   The very-low frequency sky survey of discrete sources has been obtained in the Institute of Radio Astronomy of the Ukrainian National Academy of Sciences (Kharkov, Ukraine) with the UTR-2 radio telescope at a number of the lowest frequencies used in contemporary radio astronomy within the range from 10 to 25 MHz.

GRID-based Virtual Observatory VIRGO.UA 
VO VIRGO.UA for cosmology and astrophysics is a segment of VO «Infrastructure»- a virtual organization, which deals with ensuring the provision of standards for Grid Services for virtual organizations, to ensure reliability functioning of the Ukrainian power grid, Grid training for users and administrators of the Grid sites, as well as the creation of technical conditions UNG for entry into the international grid community...
WDC-Ukraine is a part of World Data Center System of the International Council of Science (ICSU). Among the basic tasks of WDC-Ukraine there is collection, handling and storage of science data and giving access to it for usage both in science research and study process. That include contemporary tutoring technologies and resources of e-libraries and archives; remote access to own information resources for the wide circle of scientists from the universities and science institutions of Ukraine...

US VAO Data Discovery Portal 
Find datasets from thousands of astronomical collections known to the VO and over wide areas of the sky. This includes important collections from archives around the world. Feedback on your experience with the tool is appreciated -- please send your comments, suggestions, and questions to the VAO Help Desk.
US VAO Cross-Comparison Tool 
Perform fast positional cross-matches between an input table of up to 1 million sources and common astronomical source catalogs, such as 2MASS, SDSS DR7 and USNO-B. Feedback on your experience with the tool is appreciated -- please send your comments, suggestions, and questions to the VAO Help Desk.
VOPlot v1.8 Beta 
VOPlot v1.8Beta includes many enhancements and bug fixes. To name a few v1.8Beta supports multi-grid plots for 2D Scatter-Plot which allows the user to have multiple plots having grid size from 1x1 to 3x3 in a single window. Paginated view is added to see data in tabular format which allows user to navigate systematically. Provision to label Lat/Long lines is also added. Users can now plot a cumulative histogram for all histogram types. VOPlot 1.8Beta shows the metadata of a FITS file instantaneously while the actual loading happens in background. VOPlot v1.8Beta also provides better handling of "faulty data" while parsing an ASCII file.
Double Mertz-Repsold refractor-astrograph
of Kyiv university

Current status of the Astronomical Observatory of Kyiv National University (AO KNU, KAO) archive of photographic observations. According to preliminary estimates AO KNU glass collection contains about 20 thousand photographic plates. At present, in the primary mode of identifying and systematization about 4500 shots (65% of them are glass plates, others - large-format films) are partially cataloged. For the convenience of pre-cataloging approximately 200 sets of observations has been allocated, which are unevenly distributed in the timeline.

Most of the series include pictures of the photometric standards obtained on the same date. In the case of comets, exhibited by different methods, calibration images were obtained. Most plates have dimensions of 13 x 18, 13 x 13 and 16 x 16 cm, the maximum size of plates - 30 x 30 cm, the minimum (calibration ones)- 9 x 6 cm. The collection includes also some secondary images, achieved by the contact method, but their accuracy needs to be investigated as well as the accuracy of slides, obtained from plates of large size. On plates emulsions of more than 40 types were identified.

In 2010, efforts were undetaken to bring the KAO archive data of plates, which were received during the period 1898-1946 and are of historical value, in accordance with standards of IVOA.

The problems encountered during the organizing and cataloging of AO KNU glass collection are next:

  • due to two evacuations of the observatory during the WWII, not the entire archive of glass had survived, so the identification of pictures from observational logs, publications and AO KNU reports often hard to be done;
  • observations were made with more than 40 instruments, some of them no longer exist;
  • for a fairly long observation period (almost a hundred years - 1898-1996) the form of information records changed essentially many times, and some important observations are not decipherable;
  • not all observational logs are preserved.
Distribution of KAO observations in timeline

In 2010 the efforts in KAO plate collection including into Joint Database of ukrainian glass archives on the basis of MAO NASU computational facilities have started. Test digital images of near 100 historical plates were obtained with Microteck 9800 flatbed scanner and estimation of possible positional and photometric accuracies which could be reached from digital images of KAO plate collection has been conducted. The accuracy studying gives the very encouraging results of 100 mas in positions and 0.07 in magnitudes.
