We present diffraction limited K-band integral field spectroscopy of a flare associated with Sgr A*. Prom the spectrum we determined the K-band spectral index of the pure flare emission to be (F(ν) propto να) of α = -2.6 ± 0.9. If we do not subtract the quiet state emission of SgrA*, then our spectral index is consistent with earlier observations of Ghez et al. (2005, ApJ, 635, in print). We compare our observations with other data already published and discuss the implications.
