About 83% of the sungrazers observed with SOHO are members of the Kreutz group.<ref>[http://www.ast.cam.ac.uk/~jds/klist.htm Complete list of SOHO comets]</ref>  The other 17% contains some sporadic sungrazers, but three other related groups of comets have been identified among them: the Kracht, Marsden and Meyer groups.  The Marsden and Kracht groups both appear to be related to Comet [[96P/Machholz]]. These comets have also been linked to several [[meteor]] streams, including the Daytime [[Arietids]], the [[delta Aquariids]], and the [[Quadrantids]]. Linked comet orbits suggest that both Marsden and Kracht groups have a small period, on the order of five years, but the Meyer group may have intermediate- or long-period orbits. The Meyer group comets are typically small, faint, and never have tails. The [[Great Comet of 1680]] was a sungrazer and while used by Newton to verify Kepler's equations on orbital motion, it was not a member of any larger groups. However, comet [[Comet ISON|C/2012 S1 (ISON)]], which disintegrated shortly before [[perihelion]],<ref name="ARXIV-20140508">{{Cite arXiv |last1=Sekanina |first1=Zdenek |last2=Kracht |first2=Rainer |title=Disintegration of Comet C/2012 S1 (ISON) Shortly Before Perihelion: Evidence From Independent Data Sets  |eprint=1404.5968 |date=8 May 2014  |class=astro-ph.EP }}</ref> had orbital elements similar to the Great Comet of 1680 and could be a second member of the group.<ref name="GC1680">{{cite web
