Abstract
Modeling the event horizon of a black hole by a fuzzy sphere it is shown that in the classical limit, for large astrophysical blackholes, the event horizon looks locally like a noncommutative plane with noncommutative parameter dictated by the Planck length. Some suggestions in the literature concerning black hole mass spectra are used to derive a formula for the mass spectrum of quantum black holes in terms of four integers which define the area, angular momentum, electric and magnetic charge of the black hole. We also suggest how the classical bounds on extremal black holes might be modified in the quantum theory.
