We derive the infinite dimensional Supersymmetric Galilean Conformal Algebra(SGCA) in the case of two spacetime dimensions by performing group contractionon 2d superconformal algebra. We also obtain the representations of thegenerators in terms of superspace coordinates. Here we find realisations of theSGCA by considering scaling limits of certain 2d SCFTs which are non-unitaryand have their left and right central charges become large in magnitude andopposite in sign. We focus on the Neveu-Schwarz sector of the parent SCFTs anddevelop, in parallel to the GCA studies recently in (arXiv:0912.1090), therepresentation theory based on SGCA primaries, Ward identities for theircorrelation functions and their descendants which are null states.
