... Initially SAI Supernova Catalogue was presented in the form of filebased system. ... The current version of SAI Supernova Catalogue presents data on supernovae together with data on their parent galaxies. ... The main source of data for the galaxies was LEDA database. ... In some cases our data were compared with the ones from the Asiago Supernova Catalogue and from List of Supernovae at Harvard-Smithsonian Center for Astrophysics, but the compilation of our Catalogue is carried out independently. ...

... 2000 July 13 . LP 944-20: A Failed Star Flares . ... Explanation: The tiny spot circled on the right actually represents a big astronomical discovery -- the first detected flare from a failed star. Failed stars, termed brown dwarfs in astronomers' parlance , are too low in mass to ignite nuclear hydrogen burning in their cores, yet still shine feebly as the energy from their gravitational collapse is converted to heat and light. ... How did a failed star produced such a high-energy flare ? ...

... After the 2nd World War, the Executive Committee of the International Astronomical Union (IAU) made two groups in Moscow responsible for catalogues of variable stars. ... Presently, the variable-star catalogue groups still exist within the Sternberg Astronomical Institute and the Institute of Astronomy of Russian Academy of Sciences . ... Elena Kazarovets (variable stars in open clusters, Peremennye Zvezdy journal, GCVS) . ... Nataliya N. Kireeva (variable stars, globular clusters, GCVS) . ...

... Dr. Rodrigues, M1 group, Spain, has pointed out the confusion in identification of SN 1998ar in NGC 2916. ... I have measured the locations of point-like sources around NGC 2916 with DSS-1 image and 5 GSC stars. ... The magnitude of this star is estimated as 15.5 mag or so on DSS1 image. ... Star C seems to be dimmer than Star B, and comparing GSC 14.8 mag star and fainter neighbouring stars, its magnitude is about 1.5 mag dimmer than GSC 14.8 mag star; which tells that SN was about 16.3 mag. ...

THE 75th NAME-LIST OF VARIABLE STARS. ... The 75th Name-List consists of two tables. ... the literature, taken from positional catalogues, including USNO A1.0/A2.0 and GSC, or determined by the authors); the range of variability (sometimes the column Min gives, in parentheses, the amplitude of light variation; the symbol ( means that the star , in minimum light, becomes fainter, than the magnitude indicated); and the system of magnitudes used ( P are photographic ...

... The distance scales of the objects are matched both by comparing the first derivatives of the angular velocity determined separately from radial velocities and proper motions and by the statistical-parallax method. ... Good agreement between the inferred 0 and our calculations based on space velocities suggests that the Lindblad relation holds throughout the entire sample volume. ... Brandt and Blitz (1993) published the distances and radial velocities for a total of 206 H II-regions. ... Astron. ...
