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.
Mykolaiv AO stellar catalogues   27 astrometric stellar catalogues of Mykolaiv Aastronomical Observatory (MykAO) in VOTable format are available for downloading
AO KNU Historic Plate Archive   AO KNU glass collection contains about 20 thousand photographic plates. Historical part of the archive was received during 1898-1946 and now is being digitized.

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.

 Efanov Victor Alekseevich 

General data:

18.07.1932 - 16.06.1986

Studied in: All-Union extramural Energy Institute (1963);

Key interests: solar physics. PhD Thesis: The results of the study of the components of the Sun in the millimeter range of radio waves, which is slowly changing (1974 );


He was born on July 18, 1932.

Since 1956 he has been an employee of the Department of Radio Astronomy of the Crimean Astrophysical Observatory.

In 1963 he graduated from the All-Union Correspondence Energy Institute with a degree in radio engineering.

In 1974 he defended his dissertation on the topic: "The results of the study of the components of the Sun in the millimeter range of radio waves, which is slowly changing".

He died on June 16, 1983 in the Katsiveli village.

The main scientific works relate to the fields of solar physics and astrophysics. In the 1970s, he conducted centimeter and millimeter radio astronomical studies on the RT-22.

In 1969 and 1971 he took part in the first intercontinental RSDB experiments based on Simeiz - Green Bank. In 1971 he went on a research trip to the United States to process the RDB data, as well as to conduct research on the Sun on radio telescopes of the National Radio Astronomical Observatory. He developed and created the basic hardware of the 22-meter RT-22 radio telescope - a set of radio astronomical equipment in the range of 4-16 mm to study the structure and basic physical properties of active regions in the Sun. The scheme of a multi-channel 8 mm radiometer was implemented, which with the help of RT-22 allowed to record radio radiation simultaneously from five different parts of the active region on the Sun - the scheme of a radio telescope with a fan pattern. It is shown that all sources of increased radio radiation in the range of 1.35-4 mm are optically dense formations, which radiation is thermal. The close connection of the sources of the S-component at a wavelength of 8 mm with the hills of the magnetic field at the level of the photosphere in areas without groups of spots was revealed. It is shown that the direction of rotation of the polarization vector in the sources corresponds to the output of an unusual wave. Based on the study of the results of observations during the passage of Mercury to the Sun's disk, data on the fine structure of the Sun at a wavelength of 8 mm were obtained. Two types of inhomogeneities with characteristic sizes from 1.6 "to 3.4" and from 17 "to 40" were identified.
