cds-question@unistra.frnovaeobservational-astronomyThe photometric evolution of M31-RV has been investigated on 1447 plates of the Andromeda galaxy obtained over half a century with the Asiago telescopes. M31-RV is a gigantic stellar explosion that occurred during 1988 in the Bulge of M31 and that was characterized by the appearance for a few months of an M supergiant reaching M_bol_=-10. The 1988 outburst has been positively detected on Asiago plates, and it has been the only such event recorded over the period covered by the plates (1942-1993). In particular, an alleged previous outburst in 1967 is excluded by the more numerous and deeper Asiago plates, with relevant implication for the interpretative models of this unique event.2004A&A...418..869Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/418/869CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/418/869https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/418/869http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/418/869https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/418/869https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/418/869http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/418/869GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/418/869/table3Relevant information about all 1447 inspected Asiago plates of M31Nplate?
