How this entity was disambiguated
This entity first appeared as the object of triple T19730050 — 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.

Target entity: SN 2012A Context triple: [Messier 83, supernovaeObserved, SN 2012A]
-
A.
SN 2014J
SN 2014J is a Type Ia supernova discovered in 2014 in the nearby starburst galaxy Messier 82, becoming one of the closest and most extensively studied supernovae in recent decades.
-
B.
SN 2004dj
SN 2004dj is a relatively nearby Type II-P supernova discovered in 2004 in the spiral galaxy NGC 2403, notable for being one of the brightest and closest core-collapse supernovae observed in recent decades.
-
C.
SN 1987A
SN 1987A is a famous supernova, the closest observed in modern times, whose 1987 explosion in the Large Magellanic Cloud has provided key insights into stellar death and supernova physics.
-
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.
-
E.
SN 1961V
SN 1961V is a peculiar and debated astronomical transient in the galaxy NGC 1058, long argued to be either an unusual supernova or a super-outburst of a luminous blue variable star.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.
