C/2011 N3 (SOHO), also known as SOHO-2107, was a Kreutz sungrazer comet that disintegrated during perihelion on 6 July 2011.[7] In January 2012, it was revealed that the comet was also observed by the Solar Dynamics Observatory (SDO) in extreme ultraviolet (EUV) light,[8][a] providing rare insights to its actual chemical composition, mass, and nucleus size.[5]
