How this entity was disambiguated
This entity first appeared as the object of triple T18541216 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

supernova SN 1954J
Supernova SN 1954J is a mid-20th-century stellar explosion event in an external galaxy that became notable through detailed optical observations and analysis by astronomers.
-
C.
SN 1993J
SN 1993J is a well-studied Type IIb supernova that occurred in the nearby galaxy Messier 81 and became one of the brightest and most extensively observed supernovae of the late 20th century.
-
D.
SN 1572
SN 1572 is a historically significant supernova in the constellation Cassiopeia whose detailed observations by Tycho Brahe helped challenge the Aristotelian view of an unchanging heavens.
