2Astronomical data avalanche
- Breakthrough in telescope, detector and computer
technology allow astronomical instruments to
produce terabytes of images and catalogs. This
datasets will cover the sky in different
wavebands - In a few years it will be easier to dial-up a
part of the sky than wait many months to access a
telescope
3Virtual Observatory
- Over the past years the concept of the Virtual
Observatory has emerged rapidly to address the
data management, analysis, distribution and
interoperability challenges - The VO is a system in which the vast astronomical
archives and databases around the world, together
with analysis tools and computational services
are linked together into an integrated facility
4Virtual Observatories
- Sixteen VO projects are now funded through
national and international programs, and all
projects work together under the International
Virtual Observatory Alliance to share expertise
and develop common standards and infrastructures
for data exchange and interoperability - A number of the VO projects are using science
prototypes, or demonstration projects to show the
user community the benefits of the federated
archives, catalogs and computational services

7Standards are necessary
- providing access for 103 users to 107 resources

(40-50 designations for Sirius or Vega, 250
different names for Johnson V-magnitude) - names of sources like "gcvs.sternberg.on-line"

ranking, specific information (filters,
instruments, detectors, image quality etc.),
units standardisation
8What is VO?
- We will bring astronomical data from any
telescope in the world to any computer, any time,
anywhere.Parts of VO are ready now. A grand
world wide scheme 5-10 years.Less than one
Advanced Tactical Fighter aircraft.
When it will be ready?
What will it cost?

31Digitizing of glass libraries
- Russia (and fSU countries) participate in the
International project on digitizing of glass
libraries of astronomical observatories. - The project is led by Sofia Sky Archive Data
Centre. - We have got funding, and we have bought two Epson
Expression 1640XL scanners, which allow us to
scan plates up to 30x30 cm. Similar scanners are
widely used in Bulgaria as well as in Hungary and
Germany.

47Study of time sequences
Weak short transient events discovery
48NVO Brown dwarf candidate search
- BDs exhibit red (i-z) colors in SDSS and blue
(J-Ks) colors in 2MASS. - New BDs were discovered during the demonstration
of a NVO science prototype in a few minutes
(instead of weeks or months). 1/200 portion of
sky is studied. - This result was later confirmed by spectroscopic
observations on the Keck observatory

catalogues of binary stars (available only in
Russian and only in printed version). - Classification of eclipsing binaries and
determination of masses and other astrophysical
parameters of components of binary/multiple
systems. - Integration of the resulting data into the
Besancon Database of Binaries (BDB) and Virtual

53Conclusions
Russian Virtual Observatory is merged naturally
into the International Virtual Observatory. Russi
an Virtual Observatory is an open project, any
collaboration with other countries and institutes
is welcome and required (e. g., participation in
federated demos)
