... Cataclysmic Variables . ... The main aim of this survey is to discover new stellar binary systems with orbital periods less than ~80 min. ... The intensity of stellar objects can vary on a wide range of time-scales, ranging from seconds to months to years. ... Most of these surveys are sensitive to timescales longer than a day. ... For instance, the 0.3 deg x 0.3 deg survey using the Canada France Hawaii Telescope was sensitive to variations on timescales as short as ~8 min (Lott et al 2002) . ...

Prague, August 16, 2006 . The main GCVS problem is that it is no longer a GENERAL catalogue of variable stars (in fact, it even never was). The GCVS always was a catalogue of galactic variables, with a minor number of extragalactic stars that were included mainly by misunderstandings. ... Recently, many thousands of new variable stars were discovered in automatic survey projects (for example, some 30000 non-GCVS stars solely in the ASAS-3 project). ...
