Phrase: SN 1954J | Statement: [NGC 2403, supernovaObserved, SN 1954J]

Target entity: SN 1954J
Context triple: [NGC 2403, supernovaObserved, SN 1954J]

• A. supernova SN 1954J chosen
  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.
• B. 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.
• 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 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.
• E. SN 1604
  SN 1604, also known as Kepler's Supernova, was a historically significant stellar explosion observed in 1604 that became one of the brightest recorded supernovae in the Milky Way.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
