Plans for close future:

- Refresh the list of Russian astronomical on-line resouces, construct a "june 2006" version.- Register all resources in the NVO registry.- Provide an access to a pilot version of a collection of links to world- Internet resources (about 2500 links, particularly, links to principal Russian Internet resources).- Restore the INASAN mirror of VizieR; install a VALD mirror.- Organise, in cooperation with IVOA and RVO colleagues, IVOA Interoperability meeting (Moscow, Sept 2006).


19

- compiling electronic catalogs of Moscow astronomical plate collection, submitting them to the specialized international database, providing access to them by Internet;

- developing optimal techniques of scanning astronomical photographic plates using available instruments;

- scanning the astronomical plate collections of the Sternberg Institute and Zvenigorod Observatory, starting with the most valuable plates;

- studying possible ways of providing users with direct access to electronic plate scans;

- systematic updating of the GCVS information, maintenance of the updated on-line version of the catalogue, periodic releases for the CDS.

The database of Moscow astronomical plate collection,maintenance of the General Catalogue of Variable Stars


20

Current achievements:

– an electronic catalog of several thousands of plates of the Sternberg Institute's collection has been compiled;– a draft operator's manual for scanning Sternberg Institute's plates with the CREO EverSmart Supreme scanners has been prepared;– scanning Moscow and Zvenigorod plates has been started in Zvenigorod, scanning Sternberg Institute's plates has been started in Moscow in a trial mode;– the scanning laboratory in Zvenigorod has developed its Internet site;– equipment needed to keep and process data and to provide access to data obtained in the process of scanning has been purchased;– the main part of the work on preparation of the 78th Name List of Variable Stars has been finished;– the work on complete identification of GCVS stars with positional catalogs using finding charts, which took several years, has been completed. As a result, virtually all GCVS stars now have coordinates precise enough for automatic identifications.


21

Plans for near future:

– large-scale scanning of Sternberg Institute's plate collection in Moscow; – submitting several catalogs of Moscow astronomical plate collections to the specialized international database;

– revision of astrophysical GCVS information for several constellations;

– preparation of the 79th Name List of Variable Stars;

– presentation, for the IAU approvement, of suggested changes in the classification system of variable stars to be used in the GCVS and of future plans on variable-star catalogs.
