[vsnet-obs 674] Outburst Activity Database



Dear Variable Star Enthusiasts,

We are proud to announce the availability  on  Internet  (WWW)  of  a
database  with  outburst  activity  data  of 269 selected cataclysmic
variables. The database includes nearly  1000  outburst  measurements
discovered  through  1995  June,  and  is  presented with the objects
listed in order of increasing right  ascension.  For  each  outburst,
the  calendar  date  and  HJD  of  outburst  detection,  the  maximum 
brightness  attained  during  the  outburst,  the  discoverer  and  a 
reference to literature with additional information is given.

An accompanying paper (also  available  on  Internet)  discusses  the
creation  process  of  the  database, the sources of information that
were consulted, and the overall structure  of  the  database.  It  is
concluded  with a practical application of the database, by reviewing
the Cataclysmic Variables Alert Programme.

Both paper and database are currently presented at the CV Meeting  in
Keele (UK) by Steve Howell.

The Outburst Activity Database and paper are available on line at the 
WWW  site  of Steve Howell (homepage http://vsnet.psi.edu/sbhgen.html),
as PostScript files. You'll need a PostScript  previewer  to  display 
the  files  on  your  computer. Otherwise, retrieve both files, store 
them on disk and subsequently print them on a PostScript printer. 

If you have no access to PostScript devices, contact me  for  an RTF-
version of the paper and database.

We  intend  to  keep the database up-to-date and to make new releases
available over Internet on a regular basis. Your comments, input (and 
corrections) are most welcome !


Kind regards,
