SN 2014J was a type-Ia supernova in Messier 82 (the 'Cigar Galaxy', M82) discovered on 21 January 2014.[3] It was the closest type-Ia supernova discovered for 42 years, and no subsequent supernova has been closer as of 2023[update]. The supernova was discovered by chance during an undergraduate teaching session at the University of London Observatory. It peaked on 31 January 2014, reaching an apparent magnitude of 10.5.[4] SN 2014J was the subject of an intense observing campaign by professional astronomers and was bright enough to be seen by amateur astronomers.
