My name is Steve Foulkes, I have had the good luck to find SN 2000C in NGC2415. This is part of my discovery image which shows NGC2415 and the SN. ... Steve Foulkes . Image Data: . ... Object NGC 2415 recorded on 2000 Jan 8.789UT with a 0.26-m LX200 telescope on an image secured for the UK Nova/Supernova Patrol. ... The software is also used to analyse an image, and can to a limited degree, also indicate changes in the image. ... Back to Supernova 2000C in NGC 2415 . ...

... 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. ...

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 ...

... 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 ? ...

... Here is a brief outline of the current theory of the events in the early history of the solar system: . A cloud of interstellar gas and/or dust (the "solar nebula") is disturbed and collapses under its own gravity. ... The gas cools off enough for the metal, rock and (far enough from the forming star) ice to condense out into tiny particles. (i.e. some of the gas turns back into dust). ... Once the larger of these particles get big enough to have a nontrivial gravity, their growth accelerates. ...
