The seminar is supported by the grant of Federal Programm "Integration" . ... Non-triggered BATSE Gamma Ray Bursts. Extended and revised logN-logS." ... We found more GRB-like events than the yield of the similar search of Kommers et al. and extended the LogN-logP distribution down to ~0.1 ph/cm 2 /s. The indication of a turnover of the logN-logP at a small P is not confirmed: the distribution is straight at 1.5 decades and cannot be fitted with a standard candle cosmological model. ...

Prague, August 16, 2006 . To start a new GCVS edition (presumably an electronic one), combining the stars of the GCVS IV and Name Lists (and maybe eventually merged with automatic-survey variables), we need to revise the GCVS classification system. ... Our approach: the classification scheme must be simplified, more detailed classification should be given in specialized catalogs for particular types, but the GCVS classification should take into account new astrophysics. ...
