Recently, Van Dyk et.al. (2000) have speculated that supernova 1997bs, together with a few others of same type IIn, including SN 1961V in NGC 1058 and SN 1954J ("Variable 12") in NGC 2403, may more probably have been Eta Carinae-like outbursts of supermassive stars than proper supernovae explosions.

of the Sternwarte Bonn
The 17th-mag supernova is visible just right of the lower edge where the
bright lower spiral arm curves out from the central region (compare
discovery image below, and click to get a full-size version of the image
showing the SN more prominently).
