According to Official Guinness Records,

Antihydrogen, consisting of an antiproton and antielectron, or positron, is the antimatter ‘opposite’ of a hydrogen atom. In November 2010 researchers at CERN, Geneva, Switzerland, announced they had successfully trapped and contained 38 atoms of this exotic substance for around a tenth of a second.
