How this entity was disambiguated
This entity first appeared as the object of triple T21352482 — 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.

-
A.
SN 1979C
SN 1979C is a well-studied Type II supernova in the spiral galaxy M100, notable for its long-lasting X-ray and radio emission that has provided key insights into supernova evolution and their interaction with surrounding material.
-
B.
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.
-
C.
SN 1986I
SN 1986I is a supernova observed in the spiral galaxy M99 in the Virgo Cluster, notable as one of several supernovae recorded in that galaxy.
-
D.
SN 1994I
SN 1994I is a well-studied Type Ic supernova that occurred in the Whirlpool Galaxy (Messier 51), notable for its rapid light-curve evolution and stripped-envelope progenitor.
-
