B/sn Asiago Supernova Catalogue (Barbon et al., 1999-) ================================================================================ The Asiago Supernova Catalogue (Dynamic Version) Barbon R., Buondi V., Cappellaro E., Turatto M. ================================================================================ ADC_Keywords: Supernovae ; Surveys Keywords: supernovae and supernovae remnants: general - galaxies: general - galaxies: stellar contents of Description: This catalogue supersedes the previous version by Barbon et al. (1999A&AS..139..531B, Cat. II/227), and contains data about the supernovae observed since 1895 and their parent galaxies, and is regularly updated. In addition to the list of newly discovered SNe, the literature has been searched for new information on past SNe as well. The data for the parent galaxies have also been homogenized.

Note (2): lower-case bands stand for SDSS filters; '#' indicates radio discoveries Note (3): The class 'IIn?' indicates the so-called 'impostors' (super-outbursts from very massive luminous blue variables like {eta} Car) -------------------------------------------------------------------------------- History: From http://graspa.oapd.inaf.it/asnc.html ================================================================================ (End) Francois Ochsenbein [CDS] 14-Nov-2010
