NGC 2363-V1 is one of the most luminous stars known. It has been undergoing an increase in temperature and luminosity for the last 20 years, after a dramatic increase in its rate of mass loss. Significant luminosity variation within a human lifetime is rare in LBVs, e.g. Eta Carinae during its Great Eruption (1837 to 1855). NGC 2363-V1 shows an extreme B hypergiant spectrum similar to P Cygni rather than the presently cool Eta Carinae outburst spectrum.[1][2]
