Abstract: We construct infinite dimensional spectral triples associated withrepresentations of the super-Virasoro algebra. In particular the irreducible,unitary positive energy representation of the Ramond algebra with centralcharge c and minimal lowest weight h=c-24 is graded and gives rise to a net ofeven theta-summable spectral triples with non-zero Fredholm index. Theirreducible unitary positive energy representations of the Neveu-Schwarzalgebra give rise to nets of even theta-summable generalised spectral tripleswhere there is no Dirac operator but only a superderivation.
