Abstract
We present results from an odd parity test of Lorentz invariance in electrodynamics, based on a rotating microwave interferometer with permeable material in one arm. The experiment has been operating continuously since September 2007. Results set a limit on the standard model extension (SME) scalar Lorentz violating parameter, kappa(tr), of -0.8plusmn3.6times10⁻⁷.
